Bibliographic Metadata Elements (non-library)
There are a number of created element sets for bibliographic data. Most are coming from an academic research perspective and favor print materials, primarily journal articles.
- Bibliographic Ontology (BIBO)
- Citation Typing Ontology (CiTO) [part of SPAR]
- FRBR-Aligned Bibliographic Ontology (FABiO)
- Dublin Core Metadata Elements
General Metadata Elements
- Friend of a Friend (FOAF) (Foaf-o-matic)
- BIO (Biographical information)

General-use Vocabularies
Note: these are controlled lists of terms that can be used as values ("objects") in linked data. The lists included here only ones with http URIs for each term. There are many standard lists of terms that have not yet been expressed as URIs, such as many ISO lists.
- Geonames

The Open Metadata Registry
The Open Metadata Registry is a site that allows you to create RDF data sets and vocabularies in a simple user interface. It is the home to the RDA elements in RDF, as well as a number of IFLA sets, such as FRBR and ISBD.

Some Readings
Particularly for librarians
- Understanding the Semantic Web: Bibliographic Data and Metadata, by Karen Coyle. ALA Library Technology Reports, January, 2010
- RDA Vocabularies for a Twenty-first Century Data Environment, by Karen Coyle. ALA Library Technology Reports, February, 2010
- Linked Data Tools: Connecting on the Web, by Karen Coyle. ALA Library Technology Reports, May/June, 2012. v. 48, n.4
More technical readings
- Semantic web for the working ontologist by Dean Allemang, 2008, Morgan Kaufmann Publishers/Elsevier
- If you are comfortable with general metadata concepts and perhaps some database management technologies, then this is a good first book on Semantic Web metadata concepts. It's not really for beginners, but I can't find anything that is truly for beginners. So expect to struggle a bit, but the information here is solid.
- Semantic Web Programming, by John Hebeler, et al. Indianapolis, Ind., Wiley, 2009. ISBN:9780470418017
- Although this is in the end a book for programmers, the first half talks about Semantic Web concepts and standards without requiring any programming expertise. So you can learn about RDF, OWL, and see examples of uses. If you program, then the book also gets you started with some of the current Semantic Web tools: Protege, Jena and Pellet.
- Semantic Web for Dummies, by Jeffrey T. Pollock. Wiley, 2009
- In this case, the "dummy" is a fairly seasoned programmer with good skills in relational databases and object-oriented programming. So if your tech skills are good, this book will give you a lot of practical information, relating it to things you already know. It also is aimed at the business world, where terms like "enterprise" are frequently used. Although that might be a bit strange for library folks, Pollock addresses issues relating to scalability, search optimization, and the types of technical skills that are essential in this new environment.
