Abstract: In a computer system, an ontology is derived from an original data source, such as from an relational database. At any time, a user can relate useful information to an ontology node, for example, by entering a document annotation into the ontology. Later, the user can retrieve the information through the annotation and view the document together with the ontology. An ontology update scheme keeps the document annotation available even if changes in the original data would remove the corresponding portions of the ontology. In the ontology, the scheme moves the annotations from a first ontology node to a second ontology node, by following a pre-defined change pattern.

Abstract: Various embodiments described herein provide systems, methods, software, and data structures that may be used in distributed task handling. Some embodiments include a generic architecture for loosely coupled associations of globally managed tasks and artifacts within user defined task descriptions. As a result, such embodiments provide a flexible and adaptable task model.

Abstract: Embodiments include a system for providing an identification of a collaborative task. The system may include a communication unit and a processing unit. The communication unit may be configured to receive a request of a user to create the collaborative task and send task metadata to a further system. The processing unit may be configured to generate the task metadata. The task metadata may be a part of the collaborative task and identifying the collaborative task as a part of a process.
