Zeitgeist Data-Sources

XMP metadata

Asked by Alan Pater on 2013-11-28

Is there a way to have Zeitgeist read and store XMP metadata in a jpg image file? I have some wildlife photos taken with a camera trap that include DwC (Darwin Core) metadata and would like to easily search through these files. A larger project I am helping on has more then 50,000 of these images.

Hi Alan,

I'm afraid the answer is, not really.

Zeitgeist handles "events" (which have a limited set of fields), it isn't general search engine. Maybe you can find something useful here: http://www.linux.com/news/software/applications/254610-desktop-search-engines-compared

Good luck with your project!

Best regards

Thanks Siegfried. I need to rephrase the question, I think. I am wondering how to get DwC XMP metadata into zeitgeist. I understand that zeitgeist is not an indexing service.

Is it a datasource that can read and store this information feasible?

You could write a data-source to store this information, but you can only insert it as a single string (eg. in the "subject title" field), or as a binary payload that Zeitgeist will ignore (but you can access if you write a program to query those events).

So if I understand correctly, zeitgeist has a limited number of preset fields available to store results in. And the most appropriate would be the subject field. How much info can the subject field hold?

Where can I find the documentation of what fields are available?

Indeed. You can find a list of them here: http://bloc.eurion.net/archives/2012/zeitgeist-python-api-tutorial/
