The add_child message provides information about a metadata item to be added to the database. An add_child message implies that the user is adding a leaf, folder or container to a given folder or container.

Add a Node to the Tree

To add a node to the tree, the sequence of events is as follows:

  1. The client requests to add a leaf or folder to a given (editable) parent node.
  2. The Ontology server performs the following steps:
    1. Parses the node information to obtain the key / table_cd
    2. Queries the TABLE_ACCESS table for the table name associated with the TABLE_CD
    3. Inserts the new leaf, folder or container into the Ontology metadata table

  1. The client populates the selected parent node with the new node.
