Wikidata:WikiProject Linked Data for Production

Aim and scope

The aim of Linked Data for Production's Wikidata project work is an in-depth exploration of how Wikidata could serve as a platform for publishing, linking and enriching library linked data.

Background

Linked Data for Production Phase 3, LD4P3 (formerly at ld4p.org) partner institutions (Cornell University (Q49115), Harvard University (Q13371), Stanford University (Q41506), and the University of Iowa School of Library and Information Science (Q101022621)), in collaboration with the Library of Congress (Q131454) and the Program for Cooperative Cataloging (Q63468537) (PCC), are building a pathway for the cataloging community to begin shifting to linked data to describe library resources. Better integration of library metadata and identifiers with the Web through collaboration with Wikidata has been identified as a priority.

How to Create a Cradle Template

When setting up a template for Cradle, prepare by gathering the properties. Order from the most common properties (like P31) to properties which may not be used for every record but are still relevant enough to include. While Cradle doesn't do references, it does understand certain kinds of expectations for fields, e.g. a Time or a URL or an Identifier.

1. Define Header 2 for new section: use double == to surround data.
2. Put each Property on a new line, beginning with a ;. Example ;P31.
3. To make a field mandatory, put |mandatory at the end.
4. To limit or suggest possible values for a property, use either :hardselect: to create a required set of values or :softselect: to create a suggested set of values (while still allowing the person creating the item to search). Separate possible values with commas (no space). e.g.:

;P31:hardselect:Q5|mandatory or ;P31:softselect:Q1643932,Q160738,Q16645768|mandatory or ;P39:softselect:Q723682,Q1240569,Q212071,Q1255921,Q140686.

;P31:hardselect:Q5|mandatory Instance of: Human. mandatory. No other option.

;P31:softselect:Q1643932,Q160738,Q16645768|mandatory Instance of: tabletop role-playing game, or role-playing game, or storygame. Mandatory. But you can fill in another option.

;P39:softselect:Q723682,Q1240569,Q212071,Q1255921,Q140686 Instance of: dean, professor emeritus, rector, president, chair person. Not mandatory. You can fill in another option.

Sample Cradle Template

The following is the sample Cradle template I created for tabletop role-playing games:

== tabletop role-playing game ==

;P31:softselect:Q1643932,Q160738,Q16645768|mandatory

;P50

;P577

;P123

;P4151

;P856

Rationale

Community discussion forum for Wikidata related topics with the goal of understanding how the library can contribute to and leverage Wikidata as a platform for publishing, linking, and enriching library linked data.

The group will meet biweekly to discuss various aspects of Wikidata in support of the partner and cohort institution projects involving Wikidata. At each meeting, Hilary (Wikimedian in Residence) or a guest will present some relevant material related to the topic and we’ll discuss any issues members have encountered as well as helpful resources.

Anyone is welcome to join the group.

Calls

Calls biweekly, Tuesdays, 9am PDT / 12pm EDT / 16:00 UTC / 6pm CEST starting April 23, 2019
