A healthy infrastructure needs healthy funding data

We’ve been talking a lot about infrastructure here at Crossref, and how the metadata we gather and organize is the foundation for so many services - those we provide directly - and those services that use our APIs to access that metadata, such as Kudos and CHORUS, which in turn provide the wider world of researchers, administrators, and funders with tailored information and tools.

The initiative formerly known as FundRef 

Together Crossref’s funding data (previously known as FundRef  – we simplified the name)  and the Open Funder Registry, our taxonomy of grant-giving organizations, comprise a hub for gathering and querying metadata related to the questions:

“Who funded this research?” and “Where has the research we funded been published?”

Scheduled Booth Presentations at the Frankfurt Book Fair

Oktoberfest is in full swing and that makes me think that it’s almost Frankfurt Book Fair time again!

This year in addition to individual meetings we’ll have scheduled flash presentations on our booth, M91 in Hall 4.2. These short (10-minute) presentations are great for anyone wanting a quick intro to what Crossref is all about. Running on Wednesday, Thursday, and Friday - at the following times each of those days:

Crossref to Auto-Update ORCID Records

In the next few weeks, authors with an ORCID iD will be able to have Crossref automatically push information about their published work to their ORCID record. It’s something that ORCID users have been asking for and we’re pleased to be the first to develop the integration. 230 publishers already include ORCID iDs in their metadata deposits with us, and currently there are 248,000 DOIs that include ORCID iDs.

Best Practices for Depositing Funding Data

Crossref’s funding data initiative (FundRef) encourages publishers to deposit information about the funding sources of authors’ research as acknowledged in their papers. The funding data comprises funder name and identifier, and grant number or numbers. Funding data can be deposited on its own or with the rest of the metadata for an item of content.

Introducing the Crossref Labs DOI Chronograph

tl;dr http://chronograph.labs.crossref.org

At Crossref we mint DOIs for publications and send them out into the world, but we like to hear how they’re getting on out there. Obviously, DOIs are used heavily within the formal scholarly literature and for citations, but they’re increasingly being used outside of formal publications in places we didn’t expect. With our DOI Event Tracking / ALM pilot project we’re collecting information about how DOIs are mentioned on the open web to try and build a picture about new methods of citation.

♫ Researchers just wanna have funds ♫

photo credit Summary You can use a new Crossref API to query all sorts of interesting things about who funded the research behind the content Crossref members publish. Background Back in May 2013 we launched Crossref’s FundRef service. It can be summarized like this: Crossref keeps and manages a canonical list of Funder Names (ephemeral) and associated identifiers (persistent). We encourage our members (or anybody, really- the list is available under A CC-Zero license waiver) to use this list for collecting information on who funded the research behind the content that our members publish.

PDF-Extract

PDF-EXTRACT

Crossref Labs is happy to announce the first public release of “pdf-extract” an open source set of tools and libraries for extracting citation references (and, eventually, other semantic metadata) from PDFs. We first demonstrated this tool to Crossref members at our annual meeting last year. See the pdf-extract labs page for a detailed introduction to this new set of tools.

If you are unable to download and install the tool, you can play with a experimental web interface called “Extracto.” Be warned, Extracto is running on very feeble server using an erratic and slow internet connection. The only guarantee that we can make about using it is that it will repeatedly fall over and annoy you. The weasel has spoken.

Turning DOIs into formatted citations

Today two new record types were added to dx.doi.org resolution for Crossref DOIs. These allow anyone to retrieve DOI bibliographic metadata as formatted bibliographic entries. To perform the formatting we’re using the citation style language processor, citeproc-js which supports a shed load of citation styles and locales. In fact, all the styles and locales found in the CSL repositories, including many common styles such as bibtex, apa, ieee, harvard, vancouver and chicago are supported.

Content Negotiation for Crossref DOIs

So does anybody remember the posting DOIs and Linked Data: Some Concrete Proposals? Well, we went with option “D.” From now on, DOIs, expressed as HTTP URIs, can be used with content-negotiation. Let’s get straight to the point. If you have curl installed, you can start playing with content-negotiation and Crossref DOIs right away: curl -D - -L -H “Accept: application/rdf+xml” “http://dx.doi.org/10.1126/science.1157784” curl -D - -L -H “Accept: text/turtle” “http://dx.doi.org/10.1126/science.1157784”

Add Crossref metadata to PDFs using XMP

In MetadataPDFXMP

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.
