Notes on the re-implementation of the VLO

inspiration sources

• VLO 1.0: ​http://ems06.mpi.nl/cgi-bin/flamenco.cgi/flamh/Flamenco
• OLAC facet browser: ​http://syslsl01.library.upenn.edu/dla/olac/index.html

technology to be used

• SOLR for the backend
• wicket for the front-end
• CMDI for the input

data sources

• The CMDI'zed IMDI corpus: ​http://www.mpi.nl/imdi/documents/cmdi-20100713.tar.gz
• the CMDI files harvested via OAI-PMH: ​http://www.mpi.nl/imdi/documents/olac-cmdi-20101006.tar.gz

requirements

• in first instance same functionality as VLO 1.0
• using CMDI as direct input
• being reliable and debuggable
• using standardized well-maintained libraries
• a button to report errors spotted in the metadata
