Federated Timesheets Community Group

Each project has a timesheet system to track billable hours. Workers often spend time manually filling in this data multiple times. Instead, we’ll make time tracker apps (locally or on a self-hosted server) expose machine-readable timesheet data through a query endpoint (reader pull) or through a webhook (writer push). Timesheet data is relatively simple in terms of data format, data replication only flows in one direction, and there are not too many identities involved in the authentication / authorization of the data source connections. This simplicity makes the “Federated Timesheets” project an ideal case study for Federated Bookkeeping in general. We want to show case how our vision of Federated Bookkeeping can make internet users “connected but sovereign”.

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 2022-01-20 by Michiel de Jong. The following people supported its creation: Michiel de Jong, George Svarovsky, Yvo Brevoort, Andrej Bagoutdinov, Victor Emanouilov. 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.
