Tika extensions for CENDARI

Extensions of Tika to parse files and return textual contents plus metadata.

Right now, the following XML files are supported:

• EAD
• EAG
• TEI
• OAI-PMH (with embedded dc, ead, mets/mods)
• MODS
• Europeana - EDM
• The European Library (TEL) - LOD daza
• Encyclopedia 1914-1918 data format
• NERD-Only (no special metadata extraction) **PDF (any format) **.DOC (any format) **JSON (any schema)

To create a specific parser for a new XML schema, do the following steps:

1. Create a Parser class, just like eu.cendari.dip.tikaextensions.tika.xml.EADParser.java
2. Declare (add) the new class name in the file src/main/resources/org/apache/tika/META-INF/services/org.apache.tika.parser.Parser
3. Optionally add an XSLT transform in src/main/resources/eu/cendari/dip/tikaextensions/tika/xml/ to cleanup the XML file. See TEIParser.xsl for an example (and eu.cendari.dip.tikaextensions.tika.xml.TEIParser.java)
4. Add a test case in src/test/java/eu/cendari/dip/tikaextensions/TestTika.java

Note: Not all tests in TestTika are for general testing, take a look and add your own for specific testing purpose. Annotate the test with @Ignore if you do not want to run it.

Tipp for NERD: If you wish to exclude NERD for some file-types:

• populate the field CendariProperties.PROVIDER from your parser with a particular value of your choice
• add this value to the excludeList in `src/main/java/eu/cendari/dip/tikaextensions/tika/ExcludeCendariIndexer.java
