Administrative entities

  • Dataspace is a primary logical separation of data.

    Any application can define its own dataspace to store the model(s) and data it owns. Dataspace is uniquely identified by it’s name.

  • Schema Set describes a data model(s).

    Schema Set holds reference(s) to single or multiple YANG modules. Schema Set belongs to dataspace and uniquely identified by its name (within its own dataspace). Same YANG resources (source files) can be referenced by multiple schema sets from different dataspaces.

  • Anchor identifies the unique data set (data record) within a dataspace

    Anchor always references a schema set within same dataspace which describes a data model of associated data. Multiple anchors may reference same schema set. Anchor is uniquely identified by its name (within own dataspace).

Data

  • Data Node represents a data fragment.

    Each data node can have zero or more descendants and together they form a data instance tree. The data node tree belongs to an anchor.

    Data node is representing a data fragment described in a YANG model as a container and/or a list. The data described as a leaf and/or a leaf-list are stored within a parent data node.

    The data node position within a tree is uniquely identified by the node’s unique xpath which can be used for partial data query.

Querying

  • CPS Path is used to query data nodes. The CPS Path is described in detail in CPS Path.
