Supported filter options

Using the filtering options, it is possible to define more specific requests in case of several endpoints. To perform filtering, targetFilter and scopeFilter parameters can be used in the path.

Sample structure using target and scope filters:

GET https://<host>/topology-inventory/<API_VERSION>/domains/<domainName>?targetFilter=<targetFilter>&scopeFilter=<scopeFilter>

See Topology & Inventory API for all possible filter options and sample responses for each endpoint.

Querying simple entities

This functionality is supported by the following endpoints: /domains/{domainName}/entity-types/{entityTypeName}/entities

The entityTypeName is used as the root of the queries (from here referred as RootObject). Every other object, either in targetFilter or scopeFilter, has to relate to the RootObject. The queries are constructed starting from the RootObject and all other objects are joined to it. If there is no connection between the RootObject and the other object(s), the query is not constructed. The RootObject still can be retrieved and filtered using the /attributes.

Use case	domain Name	entityTypeName	targetFilter	scopeFilter	Query result
To return the ids for all instances of the entityTypeName used in the query.	RAN	GNBDUFunction			All ids of every GNBDUFunction
To return all attributes of every instance of the entityTypeName used in the query.	RAN	GNBDUFunction	/attributes		All GNBDUFunctions with every attribute
To return every instance of the entityTypeName used in the query, but only the attribute that was defined in the targetFilter parameter. Note: The attribute must be a valid field of the object.	RAN	GNBDUFunction	/attributes (gNBId)		All gNBIds of every GNBDUFunction
To return every instance of the entityTypeName used in the query, but only the attributes that were defined in the targetFilter parameter. Note: The attributes must be separated by a comma “,” when using parenthesis “()”.	RAN	GNBDUFunction	/attributes (gNBId, gNBIdLength)		All gNBIds and gNBIdLengths of every GNBDUFunction
To return the ids for all instances of the entityTypeName used in the query, that matches the given property in the scopeFilter parameter.	RAN	GNBDUFunction		/sourceIds [contains (@item, ‘SubNetwork=Ireland’)]	Unique set of ids of GNBDUFunctions, where sourceIds contains SubNetwork=Ireland
To return the ids for all instances of the entityTypeName used in the query, that matches the given attributes in the scopeFilter parameter. Note: The attributes must be separated by a AND or OR”.	RAN	GNBDUFunction		/attributes [@gNBId Length=3 and @gNBId=111]	Unique set of ids of GNBDUFunctions,where the gNBIdLength equals 3 and the gNBId equals 111
To return the ids for all instances of the entityTypeName used in the query, that satisfies one of the conditions in the scopeFilter parameter. A condition is a complete unit of scopeFilter represent OR. parameter surrounded by square brackets. Note: Multiple conditions can be given in the scopeFilter separated by a semicolon “;” to represent AND, or a pipe symbol “|” to	RAN	GNBDUFunction		/attributes [@gNBId Length=3] | /sourceIds [contains (@item, ‘SubNetwork=Ireland’)]	Unique set of ids of GNBDUFunctions, where the gNBIdLength equals 3 or the sourceIds contains an item with “SubNetwork=Ireland”

Querying connected entities

This functionality is achieved using associations and is supported by the following endpoints: /domains/{domainName}/entity-types/{entityTypeName}/entities

The entityTypeName is used as the root of the queries.

Use case	domainName	entityTypeName	targetFilter	scopeFilter	Query result
To return the ids for all instances of an entityTypeName related by an association.	OAM_TO_RAN	ENodeBFunction		/managed-by-managedElement	All ENodeBFunction entities that are managed by any Managed Element.
To return the ids for all instances of an entityTypeName related by an association to another entity specified by its id.	OAM_TO_RAN	ENodeBFunction		/managed-by-managedElement [@id = ‘urn:3gpp:dn: ManagedElement=1’]	All ENodeBFunction entities that are managed by the Managed Element urn:3gpp:dn: ManagedElement=1.
To return the attributes for all instances of an entityTypeName related by one or more associations to other entities specified by their id.	OAM_TO_RAN	ENodeBFunction	/attributes	/attributes [@enbId=1]; /managed-by-managedElement [@id=’urn:3gpp:dn: ManagedElement=1’] | /managed-by-managedElement [@id=’urn:3gpp:dn: ManagedElement=2’] ; /provided-euTranCell [@id=’urn:3gpp:dn: ManagedElement=1, EUtranCell=2’]	All EnodeBFunction entities with enbId as 1 managed by the Managed Element urn:3gpp:dn: ManagedElement=1 or urn:3gpp:dn: ManagedElement=2, and provides EuTranCell urn:3gpp:dn: ManagedElement=1, EUtranCell=2

Querying entities for relationships

This functionality is supported by the following endpoints: /domains/{domainName}/entity-types/{entityTypeName}/entities/{entityId}/relationships

The entityTypeName is used as the root of the queries.

Use case	domain Name	entityTypeName	entityId	target Filter	scopeFilter	Query result
To return the relationships for a given entity specified by its id.	RAN	GNBDUFunction	urn:3gpp:dn: ManagedElement=1, GNBDUFunction=1			All relations for the GNBDUFunction with id urn:3gpp:dn: ManagedElement=1, GNBDUFunction=1
To return specific relationships for a given entity specified by its id.	RAN	GNBDUFunction	urn:3gpp:dn: ManagedElement=1, GNBDUFunction=1		/MANAGEDELEMENT _MANAGES _GNBDUFUNCTION	All MANAGEDELEMENT _MANAGES _GNBDUFUNCTION relations for the GNBDUFunction with id urn:3gpp:dn: ManagedElement=1, GNBDUFunction=1
To return specific relationships for an entity specified by its id to another entity using its id and association.	RAN	GNBDUFunction	urn:3gpp:dn: ManagedElement=1, GNBDUFunction=1		/managed-by-managedElement [@id = ‘urn:3gpp:dn: ManagedElement=1’]	All MANAGEDELEMENT _MANAGES _GNBDUFUNCTION relations for the GNBDUFunction with id urn:3gpp:dn: ManagedElement=1, GNBDUFunction=1 where the managed element is urn:3gpp:dn: ManagedElement=1.

Querying on relationships

This functionality is supported by the following endpoints: /domains/{domainName}/relationship-types/{relationshipTypeName}/relationships

Here, the relationshipTypeName is used as the root of the queries.

Use case	domainName	relationship Type Name	target Filter	scopeFilter	Query result
To return all relationships for a specified relationship	OAM_TO_RAN	MANAGEDELEMENT _MANAGES _ENODEBFUNCTION			All MANAGEDELEMENT_MANAGES_ENODEBFUNCTION relationships
To return all relationships for a specified relationship type with a specified association to an entity.	OAM_TO_RAN	MANAGEDELEMENT _MANAGES _ENODEBFUNCTION		/managed-by-managedElement [@id=’urn:3gpp:dn: ManagedElement=1’]	All MANAGEDELEMENT_MANAGES_ENODEBFUNCTION relationships having an association managed-by-managedElement to ManagedElement urn:3gpp:dn: ManagedElement=1.

To get a relationship with a specific id, use: /domains/{domainName}/relationship-types/{relationshipTypeName}/relationships/{relationshipId}

Example: Get the MANAGEDELEMENT_MANAGES_ENODEBFUNCTION relationship with id rel1 in the OAM_TO_RAN domain:

GET https://<host>/topology-inventory/<API_VERSION>/domains/OAM_TO_RAN/relationship-types/MANAGEDELEMENT_MANAGES_ENODEBFUNCTION/relationships/rel1
