CrossRef Metadata Services, or CMS, offers an easy-to-use suite of tools for authorized partners to collect metadata on a cross-publisher basis to streamline their own crawling, indexing, and linking services. CMS includes a variety of metadata dissemination tools and provides standard terms and conditions for partners using the cross-publisher metadata available through CrossRef. Just as the core CrossRef linking service removes the need for bilateral linking agreements among publishers, the CMS program removes the need for bilateral agreements covering use of metadata between publishers and partner service providers.
Various members of the research community have announced their intent to collaborate to resolve the existing author name ambiguity problem in scholarly communication. Together, the group hopes to develop an open, independent identification system for scholarly authors. This follows the first Name Identifier Summit held last month in Cambridge, MA, by Thomson Reuters and Nature Publishing Group, where a cross-section of the research community explored approaches to address name ambiguity. A follow-on meeting of this group took place in London last week to discuss the next steps.
In order to encourage publishers and other content producers to embed metadata into their PDFs, we have released an experimental tool called "pdfmark", This open source tool allows you to add XMP metadata to a PDF. What's really cool, is that if you give the tool a CrossRef DOI, it will lookup the metadata in CrossRef and then apply said metadata to the PDF. More detail can be found on the pdfmark page on the CrossRef Labs site. The usual weasels words and excuses about "experiments" apply.
Inspired by Google's recent promotion of QR Codes, I thought it might be fun to experiment with encoding a CrossRef DOI and a bit of metadata into one of the critters. I've put a short write-up of the experiment on the CrossRef Labs site, which includes a demonstration of how you can generate a QR Code for any given CrossRef DOI.
