Re-implementing the OLAC validator

Posted on by

The OLAC validator runs off of an unit of software which has the heartbleed security vulnerability. Thinking about implementing a validator the following software comes to mind. https://github.com/zimeon/oaipmh-validator There was also an Online OAI-PMH validator from a former engineer on the Europeana project. I think he is based in Greece. His solution is not open source, but he mentioned that he would consider adding the OLAC profile. https://validator.oaipmh.com/

It would be good to see what other OAI-PMH validators look like and how submitters expect to interact with them.

OLAC Validator Custom Messages

OLAC Validator custom messages can be created following these steps:
https://xerces.apache.org/xerces2-j/faq-xs.html#faq-4

This is the software it uses for its validator: https://xerces.apache.org/xerces-p/samples/validator.html Ideally this would also be containerized with the other parts.

One approach to get this containerized might be to use this script (which is older and linux oriented) https://github.com/dgricci/xmllint

Another option is to use: https://hub.docker.com/r/isaitb/xml-validator

If this service were implemented on a new server, with a web-interface we might expect to use a newer HTML front end.

here is what I found via gitub:

https://github.com/ebruchez/darius-xml.js
https://github.com/fulvio999/jxmlutil

Darius looks more promising but neither are "out of the box" tools.
