Mulgara Documentation

Data in electronic form is flourishing. It is, in fact, growing at a rate that makes it hard to manage. Organizations often have so much information in electronic form that it can be hard to find, access, share and reuse. Mulgara is an important part of a solution to this problem.

Metadata is information about data. For example, metadata for a word-processing document or an electronic mail message might include the author, the recipients, the subject, keywords, concepts addressed, people named, dates or places mentioned. Mulgara stores this metadata and creates relationships between it.

Mulgara implements many of the World Wide Web Consortium's Semantic Web concepts (http://www.w3.org/RDF/, http://www.w3c.org/2001/sw). Mulgara databases hold metadata in the form of short subject-predicate-object statements, much like the W3C's Resource Description Framework (RDF) standard. In fact, metadata may be imported into TKS in RDF form.

Using iTQLTM (Interactive Tucana Query LanguageTM) commands, you can query Mulgara databases and receive results that match the query. iTQL is similar to the Structured Query Language (SQL) used to query relational databases, with some significant differences due to the way data is stored in Mulgara. Like relational databases, Mulgara can be used as an underlying data repository for software applications.
