EAD2RICO

Transforms

• Encoded Archival Description (EAD) 2002 XML format into
• Records in Contexts Ontology 1.1 RDF/XML (1.1 is not yet released!) 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.

1. Saxon
   1. Python with saxonche: tested with run_examples_saxonche.py
   2. JavaScript with saxon-js: tested with run_examples_xslt3.sh
2. libxml2
   1. Python with lxml: tested with run_examples_lxml.py
   2. xsltproc: tested with run_examples_xsltproc.sh

Prerequisites

• The EAD-XML file must refer to the namespace of EAD.
• /ead:ead/ead:archdesc/ead:did/ead:unitid exists, with:
  • identifier of the archive as content
  • @repositorycode for the repository

Documentation

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

Some remarks

I tried to keep the RiC-O mapping simple. This means

• I do not use Proxy-s
• I do not distinguish various Type-s (IdentifierType, RecordSetType, etc.)
• I do not distinguish various Name-s (AgentName, etc.)

RiC-O classes and properties used

Basic archival structure

• RecordSet

  • [relates to URI]
    • hasOrHadType
    • isOrWasIncludedIn
    • followsOrFollowed
    • hasOrHadInstantiation
  • [relates to BNODE]
    • hasOrHadIdentifier
    • hasOrHadTitle
    • hasExtent
    • hasAccumulationDate
    • hasOrHadMostMembersWithAccumulationDate
    • hasOrHadAllMembersWithAccumulationDate
    • hasOrHadSomeMembersWithLanguage
    • hasOrganicProvenance
    • hasOrHadLocation
    • hasOrHadHolder
    • hasOrHadSubject
  • [relates to Literal]
    • generalDescription

• Record

  • [relates to URI]
