Call for Participation in Entity Reconciliation Community Group

The Entity Reconciliation Community Group has been launched:

Matching entities across data sources using different identifiers and formats is a pervasive issue on the web.

This group revolves around developing a web API that data providers can expose, which eases the reconciliation of third-party data to their own identifiers. OpenRefine’s reconciliation API is used as a starting point. Our goals are to document this existing API, share our experiences and lessons learnt from it, propose an improved protocol in the view of promoting it as a standard, and build tooling around it.

A description of the existing protocol can be found here:

In order to join the group, you will need a W3C account. Please note, however, that W3C Membership is not required to join a Community Group.

This is a community initiative. This group was originally proposed on 2019-06-08 by Antonin Delpeuch. The following people supported its creation: Antonin Delpeuch, Ettore Rizza, Owen Stephens, Juliane Schneider, Ethan Gruber, Thad Guidry, Christina Harlow, Markus Mandalka. W3C’s hosting of this group does not imply endorsement of the activities.

The group must now choose a chair. Read more about how to get started in a new group and good practice for running a group.

We invite you to share news of this new group in social media and other channels.

If you believe that there is an issue with this group that requires the attention of the W3C staff, please email us at

Thank you,
W3C Community Development Team
