Skimming the headlines on Hacker News yesterday morning, I noticed something exciting. A dump of all the submissions to Reddit since 2006. “How many of those are DOIs?”, I thought. Reddit is a very broad community, but has some very interesting parts, including some great science communication. How much are DOIs used in Reddit?

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.

The Taxonomies Interest Group would like to invite Crossref members to an informal drop-in at the Frankfurt Book Fair: 4-5pm on Wednesday 14th October at the TEMIS booth H76 The group would like to discuss how different publishers use their taxonomies for content enrichment and to explore the role that the Crossref interest group can play in promoting industry collaboration and emerging standards.

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.

We’d like to invite the scholarly publishing community to get together in Boston this November with the Crossref Annual Meeting as a rally point. This is the event we hold just once a year to get the whole team under one roof, host a lively discussion with the leading voices in scholarly communications, present technical workshops, and offer you the chance to get hands’ on with our latest metadata services.

Publishers, researchers, funders, institutions and technology providers are all interested in better understanding how scholarly research is used. Scholarly content has always been discussed by scholars outside the formal literature and by others beyond the academic community. We need a way to monitor and distribute this valuable information.

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.

We regularly see developers using regular expressions to validate or scrape for DOIs. For modern Crossref DOIs the regular expression is short /^10.\d{4,9}/[-._;()/:A-Z0-9]+$/i For the 74.9M DOIs we have seen this matches 74.4M of them. If you need to use only one pattern then use this one.

Anybody who knows me or reads this blog is probably aware that I don’t exactly hold back when discussing problems with the DOI system. But just occasionally I find myself actually defending the thing… About once a year somebody suggests that we could replace existing persistent citation identifiers (e.g. DOIs) with some new technology that would fix some of the weaknesses of the current systems.

We’ve been collecting citation events from Wikipedia for some time. We’re now pleased to announce a live stream of citations , as they happen, when they happen. Project this on your wall and watch live DOI citations as people edit Wikipedia, round the world.

Background On January 20th, 2015 the main DOI HTTP proxy at doi.org experienced a partial, rolling global outage. The system was never completely down, but for at least part of the subsequent 48 hours, up to 50% of DOI resolution traffic was effectively broken. This was true for almost all DOI registration agencies, including Crossref, DataCite and mEDRA.
