Writing a Mozilla Application with XUL and Javascript

RDF Data Sources [ << Previous | Next >> ] ChatZilla uses the In Memory Data Source to hold user information. RDF Data Sources are objects which contain RDF data, and can be queried for that data. RDF data sources can be read/write, depending on the implementation. Any object which implements the nsIRDFDataSource interface can be treated as an RDF data source. Some data sources of interest are... An in memory data source can be used to build a graph of RDF data at runtime. A remote data source can be used to retrieve data from files and urls. A composite data source can be used to combine data from multiple datasources, giving the appearance of a single coherent source. Also, there are various component-specific implementations scattered throughout the tree. These provide RDF-like views of native data without the overhead of the (generalized) in memory data source.
