Short for XML Linking Language, a computer language that allows both unidirectional and bidirectional links to other resources (e.g., files, images, documents, programs, query results) to be embedded in XML documents, similar to the hyperlinks found in HTML Web pages.
XLink gives XML documents the ability to:
- assert linking relationships among two or more resources
- associate a link with metadata
- express links that are in a location separate from the linked resources.
