Groups are objects that can be used to organize objects within a domain. Groups contain links which can reference other objects (datasets, groups or committed datatypes). There are four different types of links that can be used:
- hard: A direct link to a group, dataset, or committed datatype object in the domain.
- soft: A symbolic link that gives a path to an object within the domain (object may or may not be present).
- external: A symbolic link to an object that is external to the domain.
- user-defined: A user-defined link (this implementation only provides title and class for user-defined links).
Groups all have attributes which can be used to store meta-data about the group.
Use the POST Group to create new Groups. Initially the new group will have no links and no attributes.
Getting information about Groups¶
Use GET Group to get information about a group: attribute count, link count, creation and modification times.
To retrieve the UUIDs of all the groups in a domain, use GET Groups.
To get a group’s attributes, use GET Attributes.
Use DELETE Group to remove a group. All attributes and links of the group will be deleted.
Note: deleting a group will not delete any objects (datasets or other groups) that the
the group’s links points to. These objects may become anonymous, i.e. they are not
referenced by any link, but can still be accessed via
GET request with the object
