Transforms

• Encoded Archival Description (EAD) 2002 XML format into
• Records in Contexts Ontology 0.2 RDF/XML with the
• XML Stylesheet Language Transformation (XSLT) 1.0.

Usage

• Use the stylesheet ead2rico.xsl, which imports all relevant sub-stylesheets.
• Use the stylesheet process-ead-in-oai-envelope.xsl if you extract your data with OAI-PMH, and want to process the raw OAI-response.

The stylesheets are intended to work with any XSLT 1.0 engine.

The file mapping.md gives an overview of all EAD-elements and in which imported sub-stylesheet the element is transformed.

Not all elements are implemented yet, especially the difficult but important mixed-content elements (inline, names) need attention.
