Catalog

From Xcri

URI:

Definition: Catalog is the default root element for XCRI’s Course Advertising schema and provides a generic container element for an XCRI feed. It prescribes one or more providers and a mandatory attribute that timestamps generation of the XML feed. A Catalog does not necessarily relate to a concept of a “Catalog” in an originating or consuming system, but rather provides the context for the content of the feed.

[edit] Guidance Notes

provider: In almost all cases there SHOULD be one and only one provider in a feed, and this should be the provider that offers the feed. The capability for supporting zero providers is offered for cases where XCRI CAP is used to format course search results. The capability for supporting multiple providers is offered to assist cases where aggregators wish to combine several feeds for processing, or for sharing feeds between aggregators.

[edit] History

v1.1 changes: Note that in v1.0 the catalog resource only contained its generated attribute and the provider; additional metadata was added in v1.1.
