The Workflow Framework (WORK) Cell is an optional i2b2 Hive cell. This cell manages project specific XML data objects for users of a given project. The project specific XML data objects originate in other views or cells, such as Ontology or Previous Query and are stored in the WORK cell as a convenience.
Project specific XML data objects in the WORK cell are organized in hierarchical structures that represent the relationships between elements. The top levels in the hierarchy are called the "parents" or "roots", with the lower levels being their "children". Elements occurring on the same level are known as "siblings". A level in a hierarchy is sometimes referred to as a "node".
The WORK cell both accepts new XML data objects for storage and provides a listing of those items previously stored. It also allows the user to organize, label and annotate the stored data objects however they choose to.
