For PUT methods, a relationship contains the vertex type +or category (related-to) and a URI that provides the identity of the +resource within A&AI. The URI can be used with the server root to +call A&AI to get more details of the related resource but cannot be +cached for long periods. (e.g., the version of the URI may get +deprecated when the release changes). + +The REST API describes each API that A&AI provides, independent of the +caller of the API, therefore there is no information to be found here +regarding the expectations on the callers. That information is +conveyed in AID documents for each client. AIDs will describe the +information expected from specific clients, but may not contain the +full payloads that would be needed on an update. Please see the +concurrency notes referenced below in order to do the right kind of +PUTs (GET, replace just what you are changing, PUT) or use the PATCH +capability. + +Deprecation Warnings and History +================================ + +AAI will maintain backwards compatibility for three prior releases. +This means, with the introduction of v14 AAI will support **v11** +(Amsterdam), **v13** (Beijing), **v14** (Casablanca), and **v16** (Dublin) + +Dublin (v16) +------------ + +Clients can call the REST API with any valid path ending in /relationship-list to retrieve just the relationship-list for that object. + +For example: + - /network/generic-vnfs/generic-vnf/{vnf-id}/relationship-list + returns just the relationship-list of relationships for that generic-vnf + - /cloud-infrastructure/cloud-regions/cloud-region/{cloud-owner}/{cloud-region-id}/tenants/tenant/{tenant-id}/vservers/vserver/{vserver-name}/relationship-list + returns just the relationship-list of relationships for that vserver + +Custom Queries for replacing named queries are now available for clients to switch to. + +Casablanca (v14) +---------------- + +- A new API called recents API is now available mostly intended for DCAE use. + +- A new and improved bulk api interface is also available now. + +- More details on the above APIs can be found in wiki pages referenced + in sections below. + +Beijing (v13) +------------- + +- To handle security vulnerabilities that were raised as part of Nexus + IQ scans in ONAP, the APIs are being hosted on a spring-boot with + Jetty web container. + +- The deletion rules are now applied to all the nodes that will be + deleted by the delete request. + + For example, if the graph is: + + +------+----------+ + |nodeA | nodeD | + +------+----------+ + + If nodeA is parent of nodeB and nodeB is parent of nodeC + + +------+---------------------+ + |nodeA | CASCADE_TO_CHILDREN | + +------+---------------------+ + |nodeB | CASCADE_TO_CHILDREN | + +------+---------------------+ + |nodeC | ERROR_IF_IN_EDGES | + +------+---------------------+ + +- If request is to delete nodeA, it would fail because nodeC has an in + edge from a node not being deleted in this transaction. + +- A configurable server timeout was implemented to make sure the AAI + server did not continue processing the request long after a client + times out on their side. An error code ERR.5.4.7406 will be returned + when this limit is hit. A configuration for clients known to have + longer running queries currently overrides the default value. + +- To handle a risk identified by Fortify scans, a maxOccurs of 5000 + was added to the XSD. + +API changes +~~~~~~~~~~~ + +- DELETE request will generate a DMAAP event for each node deleted + (not just the for which the DELETE request was made) + +- Relationship list + + Starting with Casablanca, multiple edges can exist + in the graph between the same 2 nodes. The REST API has been + enhanced via changing the relationship-list so clients can specify + which edge they are creating and differentiate multiple edges + between the same 2 nodes. Backwards compatibility with older API + versions that do notspecify the edge will be maintained. + +- A new property “relationship-label” has been added that when + specified will be used to create any new edge. If not specified the + default edge label between the two nodes will be used. The + relationship-label will always be returned with the v12 version of + GETs whenever the relationship-list is returned. + +.. code-block:: json + + { + "relationship-list": { + "relationship": [ + { + "related-link": "/aai/v12/cloud-infrastructure/complexes/complex/6d8f945d-8bd2-4fa2-ad37-36b21fc8fb23-PS2418", + "related-to": "complex", + "relationship-data": [ + { + "relationship-key": "complex.physical-location-id", + "relationship-value": "6d8f945d-8bd2-4fa2-ad37-36b21fc8fb23-PS2418" + } + ], + "relationship-label": "locatedIn" + } + ] + } + } + +Amsterdam (v11) +--------------- + +API retirements: + +- The actions/update API will be retired. Clients must switch to PATCH. + There is one grandfathered usage for vpe update flows which will be + retired in v11. + +- The edge tag query will be retired. + +Notable attribute and/or valid value changes (generally also impacts +events): + +- The persona-model-id and persona-version will be replaced with + model-invariant-id (same value as persona-model-id) and + model-version-id (the UUID of the specific version of a model). + Persona-model-customization-id will be replaced by + model-customization-id. + +- The operational-state attribute will be replaced by + operational-status and the only valid values will be in-service-path + and out-of-service-path + +- The vpn-binding object will be split in two to reflect more than one + route-target per binding. The route-target will be a child of + vpn-binding and some attributes will move from vpn-binding to + route-target. + +- The following license related attributes will be removed from + generic-vnf: license-key, entitlement-assignment-group-uuid, + entitlement-resource-uuid, license-assignment-group-uuid, and + license-key-uuid due to the introduction of the entitlement and + license children. + +Event Specific: + +- Normal impacts due to renaming or adding attributes, splitting + objects, etc. Please see swagger documentation for objects of + interest. + +- In v11, clients that require lineage, children, or relationship + information need to subscribe to a different DMaaP topic than the + current one. + +Relationship List + +- The related-link will be a URI and thus not contain + https://{serverroot} (impacts events) + +- The related-link will be used on a PUT as the "first choice" to + identify the related resource. The relationship-data structure, which + contains the unordered set of keys, is still an acceptable way to + relate two objects but, *if both the relationship-data and the + related-link are passed, and they don't agree, the related-link will + be used without warning that the data is inconsistent*. + +- The relationship-data will be ignored on PUT. + +Future Warning +============== + +In the future, the hope is that individual node definitions will be +separately versioned from API behavior and from one another (e.g., +vserver hasn't changed in many releases and so doesn't need to have +its "definition" version updated). + +Because relationships are starting to become more complex, it may be +necessary for AAI to expose to clients the exact relationship between +two nodes. This will likely be done with a relationship-type +attribute of relationships in the relationship-list. + +To support the concept of events getting generated on specific changed +items, AAI will be migrating towards a model of asking clients to do +the most granular PUTs possible rather than leveraging the nested +elements of a tree structure. + +The vce, port-group, cvlan-tag, newvce, vpe, oam-network, and +dvs-switch objects will eventually be deprecated in favor of +generic-vnf, l3-network, ctag-assignment, segmentation-assignment, and +TBD. + +L3-network will eventually be replaced by virtual-network. + +How to Use this Document +======================== + +The only attributes in our objects that are declared required are +those which we know will be present at the creation of each object and +which are needed to support the construction of the AAI Graph. This +does not imply that one of AAI's clients doesn't need data. + +When you click on the API documentation, you will see the Summary of +APIs broken down by namespace (e.g., cloud-infrastructure, business, +network, service-design-and-creation). You can search for **Tag:** +(matching the explicit case) to move from namespace to namespace through +the Summary. + +Search for **Paths** to skip past the Summary section where there will +be more detail about each API. Query parameters are provided here, as +well as links to our error codes. + +Search for **Schema definitions** to see the definitions of the +payloads. In your browser URL, you can type /#/definitions/node-name at +the end of the html address to skip directly to a payload definition. + +Note that the schema definitions now contain information about the +delete scope of a node, edges, and some related node information. +Given this information can now be generated, it is no longer repeated +in this document. + +Once AAI has a model and configured it, the AAI development server can +be used to generate sample XML and JSON payloads, according to the +Accept header passed in the request. This is done by calling the +"plural" version of an API followed by the word example (e.g., +/vserver/vservers/example). This returns a GET result array with one +entry. That single entry can be sent in a PUT request with actual data +(the resource-id does not need to be in the PUT payload as it is on the +URL). + +Finally, custom queries that are not simple GETs of a resource must be +identified to AAI as separate user stories. This includes searching +for a resource with other attributes on the same resource, as well as +searching for resources based on their relationship with other +objects. + +AAI API Definition +================== + +Namespaces +---------- + +Cloud Infrastructure Domain +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The Cloud Infrastructure domain (cloud-infrastructure) represents the +assets managed within a cloud site. This includes the complex, the +physical servers, the availability zones, oam-networks, tenants, and +vserver-related resources (vservers, flavors, images, etc.). + +Tenants, oam-networks, availability-zones, volume-groups, images, +flavors, and dvs-switches will have cloud-region as its parent node. + +Network Domain +~~~~~~~~~~~~~~ + +The network namespace contains virtual and physical network resources +as well as connection resources such as physical links, logical links, +lag links, etc. + +The vce/port-group/cvlan-tag tree represents an immature model that +blended several resources together in ways that were expedient but +which need to be re-evaluated. A newvce object exists which was the +basis of the generic-vnf object. Future efforts will attempt to +migrate vce and vpe into generic-vnf. + +Business Domain +~~~~~~~~~~~~~~~ + +The business namespace captures customers, service-subscriptions, and +service-instances. This domain is immature and will be evolving as +service design and creation starts to gel. + +Customers and service-subscriptions in particular will be evolving +soon. Any service that is customer facing will see customer and +service-subscription data offboarding to BSSs. The +service-instance-id will be the "join point" within the BSS to +correlate the service-instance to the product and customer. Services +that are for infrastructure purposes will have a new entity, an +owning-entity, to replace the customer. The owning-entity will be +related to the SDC service models that use it. + +Service Design and Creation +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The service design and creation namespace captures data we invented +based on what we thought SDC would eventually provide. The structure +of that data is definitely not what the current plans are for SDC +however we need to at least capture the spirit of what's intended and +communicate that across ONAP sub components that need it. + +To date, there are only five containers: + +1. Service-capabilities capture the pairings of service to + resources. At the time of construction, the only data we had to + denote service was the service-type from SO. The vnf-type is the + resource. + +2. Service captures the service model instances and this will be + deprecated in the future as things mature + +3. Vnf-image captures information about the resource image needed for + a VNF. This was created due to there being no info available on + the vservers that run on uCPE + +4. Models captures model definitions (subgraph definitions using the + AAI widgets) + +5. named-queries capture subgraph definitions that allow different + data to be retrieved for a given type of asset + +Security +-------- + +All REST APIs must be called using https. + +HTTPS Basic Authentication will be used to authenticate clients. The +remote user from the HTTP Servlet Request is used against an AAI +policy to see if the authenticated user is authorized for the resource +and actions being request. + +Client should use credentials provided to their system via AAF. + +Headers +------- + +The following will be used for logging and interface diagnostic purposes. + + * X-FromAppId Unique Application ID assigned to the user of these APIs + * X-TransactionId Unique ID that identifies an API request + +The X-FromAppId will be assigned to each application by the AAI team. +The X-TransactionId must be unique to each transaction within the +context of an X-FromAppId. + +SO, SDN-C, and AAI have agreed to use the Java UUID class to generate +unique ids for X-TransactionId. + +The Accept and Content-type header should be set to either +application/json or application/xml except as documented for PATCH. + +Response Codes and Error Handling +--------------------------------- + +AAI will use the following HTTP codes + +HTTP Codes: +~~~~~~~~~~~ + +- 200 – Success +- 201 – Created +- 202 - Accepted +- 204 – Success, no payload returned +- 400 - Bad Request +- 401 - Unauthorized +- 403 - Forbidden +- 404 - Not Found +- 405 – Method Not Allowed +- 409 - The request could not be completed due to a conflict with the + current state of the target resource.

On the first line, substitute the appropriate status response code. + +b. On the second line, substitute the appropriate content type. + +c. Express the requestError structure in the required content type (e.g., either JSON or XML). AAI will use JSON. + +d. ‘requestError’ contains either a ‘policyException’ or a ‘serviceException’ structure. + +e. url is optional + +In 1512, AAI is introducing a response payload that is possible during a successful PUT. This payload is used to inform the client that, while AAI completed the action requested, the result could be interpreted as a warning or request for additional action, as negotiated with the client. + +Sample response to a vserver PUT where the pserver and complex did not exist: + +.. code-block:: json + + {"responseMessages": {"responseMessage": [ + { + "messageId": "INF0003", + "text": "Success with additional info performing %1 on %2.

The referential integrity rules of AAI are +still evolving as we understand the services and customers that will +use us. + +AAI uses a graph database on a NoSQL data store. The following are +true for AAI: + +* Some vertices are exposed to the outside world through APIs, others + are internal to how we store the data (i.e., it may look like one + resource to our customers but it is expressed as more than one + vertex in our graph) + +* Vertices that are internal to AAI will be deleted when the parent + vertex is deleted, if deletion of the parent leaves the child vertex + orphaned + +* Vertices that are exposed need to be managed using specific rules + for each vertex. + +* Vertices may have more than just parent/child relationships. One + example is a vserver, which will be owned by a tenant and used by a + VNF. + + +URLs Sent To and Retrieved From A&AI +------------------------------------ + +A&AI receives URLs from clients that point back to that client in +order to get more details about the data sent to A&AI. A&AI expects +the URLs sent by clients (e.g., self links) to be URL encoded +(UTF-8) and A&AI will store them unchanged. + +URIs that A&AI constructs that point to A&AI resources will be +returned URLEncoded (UTF-8) to clients. This affects URIs in +relationship lists and search results. Note that A&AI used to send +URLs but, as reported in the 1707 impacts, these will now be URIs. + +A&AI expects space to be %20, and not plus(+). + +The Relationship-List +--------------------- + +The REST interface does not lend itself to creating more than +parent-child relationships and the backend structure of AAI is a +graph. A goal of AAI, and shared with ONAP, is to do as little coding +as possible to introduce a new service into the service design and +creation environment. + +To that end, we've introduced a relationship-list structure. AAI will +ask its clients to provide certain data in the relationship-list +structure. + +Each relationship has a related-to attribute and a list of key/value +pairs. The related-to attribute identifies the node type that the +resource being acted on is to be related to using the data in the +key/value pairs. AAI will encode a set of rules for each resource +type to verify that only valid edges are being made. AAI will keep +the directionality and cardinality, and the edge attributes within its +own logic. In the near future, the definition of relationships, their +validity, and cardinality will be captured in the ONAP TOSCA models. + +AAI also has a concept of a related-to category. To date, the only +category is vnf. The vnf category is used as the related-to value to +indicate that the relationship being establish is to a Virtual Network +Function of unknown type. The vnf-id happens to be unique for all +services across all nodes in the graph. By providing vnf.vnf-id with +a specific value, AAI can look at all VNFs in the graph and find the +appropriate vertex. Note that this only applies to PUTs. + +Category vnf is used for node types of vce, vpe, and generic-vnf. + +If an attempt is made to add a relationship to a node that doesn't +exist (e.g., from a vserver to a vnf, and the vnf doesn't exist), a +unique message Id (3003) will be returned with a specific error code +(ERR.5.4.6129). Arguments will tell the client which node type was +missing (e.g., vnf) and the key data for that node type (vnf.vnf-id). + +Single relationships can be PUT to the graph in the following way: + +.. code:: + + https://{serverRoot}/{namespace}/{resource}/relationship-list/relationship + +or + +.. code:: + + https://aai.onap:8443/aai/v16/cloud-infrastructure/pservers/pserver/pserver-123456789-01/p-interfaces/p-interface/p-interface-name-123456789-01/l-interfaces/l-interface/l-interface-name-123456789-01/relationship-list/relationship + +with a payload containing the relationship information. + +AAI will accept and give preference to the related-link URI + +XML + +.. code-block:: xml + + <relationship xmlns="http://org.onap.aai.inventory/vX"> + <related-link>*/aai/v10/network/logical-links/logical-link/logical-link-123456789-01*</related-link> + <related-to>logical-link</related-to> + <relationship-data> + <relationship-key>logical-link.link-name</relationship-key> + <relationship-value>logical-link-123456789-01</relationship-value> + </relationship-data> + </relationship> + +JSON + +.. code-block:: json + + { + "related-link": " /aai/v10/network/logical-links/logical-link/logical-link-123456789-01", + "related-to": "logical-link", + "relationship-data": [ + { + "relationship-key": "logical-link.link-name", + "relationship-value": " logical-link-123456789-01" + } + ] + } + +Health Check API +---------------- + +The util domain is where AAI locates utility functions.

Port and base path are OPTIONAL but AAI will use port 8443 and base path aai. Note that the base path may change before production, so please make this configurable. Versions will change as releases are made. + +* {namespace} refers to the API namespace. Supported namespaces are cloud-infrastructure, business, service-design-and-creation, and network + +* {resource} refers to how the object is identified according to the namespace specifications. + +Example GET Request + +.. code:: + + GET https://aai.onap:8443/aai/v16/cloud-infrastructure/cloud-regions/cloud-region/{cloud-owner}/{cloud-region-id} + +Swagger and XSD: +---------------- + +`Offered APIs <../platform/offeredapis.html>`_ + +Data Assumptions +---------------- + +Given AAI is largely a correlation engine among disparate inventory +types, AAI will for the most part accept values as they are sent, +without validating the format or value of the input. **It is +incumbent upon the source of truth to provide valid information to +AAI.** + +Clients should either use the PATCH API to only change +the attribute values they mean to change, or do a GET prior to a PUT +and change only the data that they mean to affect. + +The PUT REST APIs expect the payload passed to replace the resource in +AAI. **A GET before PUT is vital in our concurrency scheme. The +client will be returned an opaque value per entity which needs to be +returned back in the PUT. AAI will reject the PUT or DELETE if the +opaque value doesn't match what AAI has stored for that entity.** + +If an attribute has been added to a model in vN+1, and a GET/PUT of a +vN resource is done, AAI should not affect the new attribute (i.e., it +should be left unchanged). + +Concurrency Control +------------------- + +Concurrency control for AAI is in place. + +* A client always gets a resource before updating through PUT or deleting it. + +* All resource updates and deletions are done via the AAI REST APIs + +* This solution will apply to PUT and DELETE operations. + +* The resource-version attribute is now in every container + +* The PATCH REST verb is not subject to concurrency control, because + it is only intended to be used by clients who are the definitive + source of truth for the attributes they are changing. An update + through the PATCH API will however reset the resource-version so + clients using PUT and DELETE will not risk updating with stale data. + If a client would like us to do concurrency control for PATCH, we + will need a feature request. PATCH is recommended for clients who + know they are the definitive source of data, as there is less risk + of destroying other data. + +If you use PUT, you MUST send back the entire resource, not just the +pieces you know about. This is best illustrated by example. Note: +Specific interfaces only show you the data you are responsible for but +that does not mean that's all the data that the resource you GET will +contain. You are responsible to overlay only your changes and leave +everything else untouched. + +Imagine this is the existing resource: + +.. code-block:: json + + { + "node-id": "valueOfNodeId", + "node-name": "valueOfNodeName", + "prov-status": "NVTPROV", + "relationship-list": { + "relationship": [ + { + "related-link": " /aai/v16network/generic-vnfs/generic-vnf/generic-vnf-20160902a", + "related-to": "generic-vnf", + "relationship-data": [ + { + "relationship-key": "generic-vnf.vnf-id", + "relationship-value": "generic-vnf-20160902a" + } + ] + }, + { + "related-link": " /aai/v16/network/generic-vnfs/generic-vnf/generic-vnf-20161010", + "related-to": "generic-vnf", + "relationship-data": [ + { + "relationship-key": "generic-vnf.vnf-id", + "relationship-value": "generic-vnf-20161010" + } + ] + } + ] + }, + "resource-version": "1474912794" + } + +And you want to update the name and add a relationship to an l3-network. + +The payload you need to send back, if you choose PUT, is this. The +node-name and the third relationship block is the new data, and the +other data and relationships previously existed and must still be PUT. + +.. code-block:: json + + { + "node-id": "valueOfNodeId", + "node-name": "NEWvalueOfNodeName", + "prov-status": "NVTPROV", + "relationship-list": { + "relationship": [ + { + "related-link": " /aai/v16/network/generic-vnfs/generic-vnf/generic-vnf-20160902a", + "related-to": "generic-vnf", + "relationship-data": [ + { + "relationship-key": "generic-vnf.vnf-id", + "relationship-value": "generic-vnf-20160902a" + } + ] + }, + { + "related-link": " /aai/v16/network/generic-vnfs/generic-vnf/generic-vnf-20161010", + "related-to": "generic-vnf", + "relationship-data": [ + { + "relationship-key": "generic-vnf.vnf-id", + "relationship-value": "generic-vnf-20161010" + } + ] + }, + { + "related-link": " /aai/v16/network/l3-networks/l3-network/network-name-for-me", + "related-to": "l3-network", + "relationship-data": [ + { + "relationship-key": "l3-network.network-name", + "relationship-value": "network-name-for-me" + } + ] + } + ] + }, + "resource-version": "1474912794" + } + +A Warning About PUT and Lists +----------------------------- + +The PUT verb is used to both create and replace a resource. A given +resource may have child resources (e.g., customers have service +subscriptions, generic-vnfs have vf-modules, tenants have vservers and +vservers have volumes). + +The following convention will be followed: + + If a resource is replaced and there are no tags for children, the + children that exist will be left alone. + + If a resource is replaced and there are tags for children, the + children will be replaced by the list passed. If the list is empty, + then children will be deleted. + +Note that the relationship list is a type of child resource. The same +conventions are followed. It is especially critical to ensure that +you do not send an incomplete relationship list and therefore remove +edges in the graph. See `The Relationship-List`_ for more information on +relationship lists. See `Concurrency Control`_ for an example of GET followed by +PUT containing the entire resource (i.e., overlaying your changes on +what already exists so that you don't wipe out other data). + +PATCH +----- + +To move towards industry standards and to make our APIs easier to use +by clients who own specific attributes and do not require AAI to +enforce concurrency control around them, the PATCH verb has been +introduced. + +.. _RFC 7386: https://tools.ietf.org/html/rfc7386 + +- RFC Algorithm implemented JSON Merge PATCH: `RFC 7386`_ +- HTTP Verb = PATCH +- Clients can send a POST with "X-HTTP-Method-Override" = "PATCH" and + Content-Type = "application/merge-patch+json" to send a PATCH + request to AAI. +- PATCH does not support XML +- PATCH does not require a resource version to perform these modifications +- Clients should only send what they wish to modify and whose value they "own" +- PATCH returns a 200 with no response body for success + +Example: + +.. code:: + + PATCH https://aai.onap:8443/aai/v16/network/generic-vnfs/generic-vnf/cscf0001v + { + "vnf-id": "cscf0001v", <-- This key needs to be here but you cannot modify the key + "regional-resource-zone": null, + "ipv4-oam-address": "10.10.99.11" + } + +This payload would result in the generic-vnf with the vnf-id = +cscf0001v having ipv4-oam-address set to "10.10.99.11" and +regional-resource-zone having its value removed from the database. + +Note: PATCH is used only to update attributes on a single node that +already exists in AAI. That means it is not applicable to lists of +any type. + + * You do not manage relationships with PATCH. There is a + relationship API for that. + + * You cannot include child objects in a PATCH payload, i.e., you + cannot PATCH an l3-network's attributes as well as supply some + subnet children or their attributes within the same PATCH payload. + You can GET/overlay/PUT parent/child payloads or you can PUT or + PATCH each object individually with separate REST API calls. + +Optional Query Parameters +------------------------- + +A **depth** query parameter is available allowing a query to stop after it +has reached a certain point in the graph. This allows clients to +minimize the data that is returned to them and make the queries more +performant. A depth=0 will return information of the node referred to +by the URI only without any information on the children. + +Example + +.. code:: + + GET https://aai.onap:8443/aai/v16/cloud-infrastructure/cloud-regions/cloud-region/{cloud-owner}/{cloud-region-id}?depth=0 + +A **nodes-only** parameter is available allowing a query to only +display the properties of the nodes being queried without any +relationship information. This allows clients to minimize data that is +returned to them and make the queries more performant. + +Example + +.. code:: + + GET https://aai.onap:8443/aai/v16/cloud-infrastructure/cloud-regions/cloud-region/{cloud-owner}/{cloud-region-id}?nodes-only + +These parameters may be used in combination with each other. + +Example + +.. code:: + + GET https://aai.onap:8443/aai/v14/cloud-infrastructure/cloud-regions/cloud-region/{cloud-owner}/{cloud-region-id}?depth=0&nodes-only + +Delete Scope and Edges +---------------------- + +An attempt to remove a node which would result in a delete scope being +violated will return error 5.4.6110. + +The swagger documentation has been updated to show information about +delete scope and edges. + +Here is a subset of the generic-vnf definition that will be used to +demonstrate how the delete scope and edges are documented. + +The following table summarizes actions AAI will take upon deletion of a resource, i.e., its default delete scope: + ++-----------------------------+--------------------------------------------------------------------+ +| ERROR_IF_ANY_EDGES | If the resource being deleted has any edges at all | +| | an error should be returned | ++-----------------------------+--------------------------------------------------------------------+ +| ERROR_IF_ANY_IN_EDGES | If the resource being deleted has any edges that point IN towards | +| | it, an error should be returned | ++-----------------------------+--------------------------------------------------------------------+ +| THIS_NODE_ONLY | Delete the vertex being requested by first deleting its edge to | +| | other vertices, but do not delete the other vertices.

An error code ERR.5.4.7406 will be returned when this +limit is hit. The default value for Resources API is 60 secs. The +clients should set their timeouts accordingly. + +Bulk APIs +--------- + +The Bulk API allows clients to make multiple requests in a single +transaction. Please look for additional details on the following wiki +page: `Bulk API <bulkApi.html>`_ + +AAI Traversal APIs +================== + +Not all queries of the graph are purely GETs of a specific resource +and its related vertexes. The following capabilities are available to +meet more advanced search needs. Please contact the AAI team if you +need another search. + +Node Queries +------------ + +The Nodes Query mechanism was implemented in support of searching the +pservers which do not have the ipv4-oam-ipaddress set. It will allow +nodes to be searched based on certain properties of the nodes. It will +allow search based on properties being set, not set or set to specific +values. + +Please reference `Node Queries <nodeQueries.html>`_ for details on the +API and test queries. + +Nodes API +--------- + +In working with A&AI's standard REST API, you may have noticed that +certain API paths have a hierarchy to them and require a client to +know multiple object keys to preform GETs. For example: the vserver +object is under tenant, which is itself under cloud-region. If you +wanted to look up a vserver by name, you would still need to know the +tenant-id and cloud-region-id (and cloud-owner) in order to +successfully perform that GET. The nodes API allows for more freedom +in querying A&AI, allowing clients to circumvent the need to know +every key in the hierarchy. + +See `Nodes Query <nodesQuery.html>`_ for more information. + +Generic Queries +--------------- + +The Generic Query mechanism allows to search for certain nodes of +“include” node types at a specified “depth” from the from a particular +start node of type “start-node-type” identified by specifying its +“key” values + + + +Model Based Query and Delete +---------------------------- + +AAI supports a search and delete capability that allows a client to +retrieve or delete an instance of a service based on the model +subgraph definition provided to AAI by ASDC. + +The instance filters must uniquely identify a service instance. + +The URL is as follows: + +.. code:: + + https://{serverRoot}/aai/search/model[?action=DELETE] + +.. code-block:: json + + { + "query-parameters": { + "model": { + "model-invariant-id": "$modelInvariantId", + "model-vers": { + "model-ver": [ + { + "model-version-id": "$modelVersionId" + } + ] + } + }, + "instance-filters": { + "instance-filter": [ + { + "customer": { + "global-customer-id": "$globalCustID" + }, + "service-instance": { + "resource-version": "$resourceversionID", + "service-instance-id": "$serviceInstanceID" + }, + "service-subscription": { + "service-type": "$serviceType" + } + } + ] + } + } + } + +Named Query +----------- + +These queries provide the ability to upload a json file describing the +inputs and designed output based on traversing the graph in a +particular way. Existing named queries are supported but will be +migrated to custom queries. **Named queries will be deprecated (no new +queries, just support for existing ones) in Dublin and clients will be +asked to migrate to use the custom queries instead.** + +Custom Query +------------ + +This API provides AAI clients an API for complex data retrieval. To +execute a custom query, a client will perform an HTTP PUT request on +the query API and include a payload indicating the starting node and +the query to be run. While the client is performing a PUT request, +this is actually a data query and no data is created or changed. + +Assumptions +~~~~~~~~~~~ + ++----------+-----------------------------+--------------------------+ +| No. | Assumption | Approach | ++==========+=============================+==========================+ +| 1 | Assume that client will | | +| | not request large amounts | | +| | of data from AAI w/out | | +| | using secondary filters | | ++----------+-----------------------------+--------------------------+ + +Depdendencies +~~~~~~~~~~~~~ + +Data has been PUT to AAI prior to the query. + +Custom Query URI +~~~~~~~~~~~~~~~~ + +.. code:: + + PUT /aai/v$/query?format={format} + +Query Formats +~~~~~~~~~~~~~ + +The format determines what information is returned from the +query.
