these innovations represent opportunistic growth

good ideas

lets give it a try

Third round expansion

CrossRef Funding Data

• based on a core competency: centralized metadata collection and distribution

• define an emerging competency: uniform APIs enabling platform building

this is crossref data retrieved in real time from crossref

crossref funding data + crossref APIs + crossref metadata infrastructure

a foundation for the Chorus platform=

This capability is openly available to anyone.

crossref currently has 3 working groups focused on specific issues

1) publishers and funding agencies developing fundref2) standards bodies redesigning metadata deposits and query

services to better support Standards3) book interest group driving change to deposit work flows

to accommodate real world practices in book content hosting.

working groups

Common characteristics for working groups

• typically lead by a crossref member (staff administrates)• participants are members and non-members• autonomous• mostly goal oriented (exist until task accomplished)• scope/mission may be broader than a crossref-specific issue

working groups

research data

128 members have deposited 1064 database titles798,925 database itemsSome ‘database’ deposits are actually reference works

There are ‘legitimate’ databases

• DOIs can be created for database content• components (parts that make up an article) can be data items*• publishers can cite database DOIs * in the article bibliography• data DOI owners* can query crossref to see who cites their data

Currently:

publishers will be able create typed relationships between the article and the data* it makes use of (e.g. alternative to a formal citation)

1st QTR 2015:

research data

* these can be crossref or DataCite DOIs

research data

crossref is committed to DataCite interoperability

engage our existing member constituency who are creating DOIs for data to identify and solve issues related to DOIs for data

what else can we do

(include participation by non-crossref members)

create a new content type so that DOIs classified as ‘data’ can be correctly reclassified

research data

proper recognition of research data faces the same seminal problem addressed by FundRef for funders:

formalize the process of attribution

• DOIs provide part of the process• a bigger part comes from community action

ecosystem*:

community of living organisms in conjunction with the nonliving components of their environment
