Hmm, very interesting! I didn't know about the embedding metadata, that is brilliant. But who does it and is the vocabulary standardized?

Good questions, Carol. I will see what I can find out.


Part of EPUB is the standard OPF (Open Packaging Format) which contains the metadata. They are based on Dublin Core. Here's a useful summary: http://blogs.ukoln.ac.uk/ap-support/2010/12/ and here's more on metadata in the EPUB spec: http://idpf.org/epub/30/spec/epub30-publications.html#sec-metadata-elem. Not sure who creates the metadata, though - the publisher?

Thanks for these links! I will take a closer look a the EPUB spec. I suppose the publisher (with input from authors) would be the logical creator for EPUB metadata. So, I'm thinking libraries could just extract and repurpose EPUB metadata as needed.


Christine - I think the general future of cataloging is batch processing. The types of batch processing are going to vary depending on the type of library. I can foresee public libraries sticking to copy cataloging en masse.

Academic libraries will see more detailed extraction and re-purposing of the metadata. They will continue doing batch processing on records for resources purchased but that will be a small portion of the job. Increasingly the descriptive metadata will be done via extraction on resources going out (i.e. repository materials) Then there will be re-purposing of the metadata into other systems (identity management, citation tracking, etc.).

This is why those programming skills you're acquiring will come in handy. I believe academic catalogers roles will only become more technical. Essentially we will be bit-movers, helping metadata interoperate between systems.


I've looked at the metadata on some of the ebooks I got - the standard is going to have to improve. I've only looked at a few, but when, eg, the publication date isn't included it would be a problem
