An Extended vocabulary based on RDF/FOAF
This extended RDF vocabulary will describe persons, institutions, enterprises, publications, events, projects, areas of expertise and interests...Starting with FOAF we want to identify and reuse as much as possible existing RDF vocabularies or de facto standards in other related formats such as XML Schemas. FOAF might already cover a big part of persons, and we might decide to recommend the use of particular ontologies for annotations of institutions, publications, areas of expertise, community events, etc.
Describing Bibliographic Data
The MarcOnt initiative combines the MARC21 bibliographic description format with Semantic Web technologies to describe publications. SwetoDblp is a large-size ontology (spin-off of SWETO ontology) focused on bibliography data of Computer Science publications where the main data source is DBLP. AndreasHarth already gathered some experience of DBLP2RDF export which he used for importing DBLP data into YARS.
For BibTex which is a de facto stanbdard within the scientific community for descrbibing bibliographic data there exist several RDF versions, where the first one appears to be the most widely used at the moment:

Describing Persons and Institutions
Here FOAF already covers quite a bit, still some other exitsing vocabularies can be fruitfully reused in order to extend FOAF with necessary features. vCard which offers a fine grained vocabulary for describing address data, persons is a de facto standard for import and export in various existing tools. KnowledgeWeb on People's portal application imports the Person-related part of the KnowledgeWeb ontology, and provides an opportunity for any portal user to introduce ontology extensions and reuse them in a community-oriented way.
There are various RDF versions of iCal which could provide valid starting points to annotate events properly

Related Initiatives and Projects
The SemNetMan project on Social Networking and Semantic Web extracts RDF instances linking persons and their interest from a Forum Database, using a project specific ontology for people and topics they are interested in. SPICE is a mobile communications project with activities on ontologies and knowledge-based systems, group management.
The RDFHomepage from DFKI is another related interesting project which has the goal to provide means for creating homepages from pure RDF data.
