Artifacts

Crossref maintains a number of Artifacts. These are individual pieces of information that we have produced internally which enable Agents or other parts of the Event Data system to do their job. They contain information like:

  • the list of domains where we think we'll find Publisher Landing Pages
  • the list of DOI prefixes
  • the list of available sources

Every Artifact has a label and a version number. Whenever one is used, its label and version number are mentioned in an Evidence Record. This way you can trace the provenance of an Event all the way back. For example you may wish to know why an Event was captured for this Landing Page domain but not this one. The Artifact will tell you which domains we knew about, when.

Here are the current Artifacts in use:

Name Purpose
domain-decision-structure List of Domains, Prefixes, and the link between them.
crossref-sourcelist List of sources that are available in the Crossref Query API.
datacite-doi-prefix-list List of prefixes that are issued to DataCite members.
newsfeed-list List of RSS and Atom feeds that the Newsfeed Agent follows.
stackexchange-sites List of StackExchange sites that the StackExchange Agent follows.
subreddit-list List of Subreddits that the Reddit Agent follows.

You will see Artifacts mentioned in Evidence Records when they are used by Agents. You can browse all of the Artifacts, including their previous versions in the Artifact Registry.

Deprecated Artifacts

The domain-decision-structure Artifact contains a list of all domains, prefixes, and the relationships between them. You may see the following Artifacts linked to historical data.

Name Purpose Consolidated into
crossref-doi-prefix-list List of prefixes that are issued to Crossref members. domain-decision-structure
crossref-domain-list List of Domains that resolve from Crossref DOIs. domain-decision-structure
datacite-domain-list List of Domains that resolve from DataCite DOIs. domain-decision-structure
doi-prefix-list Union of crossref-doi-prefix-list and datacite-doi-prefix-list. domain-decision-structure
domain-list Union of crossref-domain-list and datacite-domain-list. domain-decision-structure
exclude-domains Domains that should be ignored, e.g youtube.com domain-decision-structure
