Solid Data Interoperability Panel

Join the chat at


We must be able to support data interoperability across applications while enabling secure collaboration and query using intuitive data boundaries.

Diversity in how the same data will be accessed and manipulated by different entities and applications increases the need for reliable mechanisms that protect against data corruption, data leakage, or broken workflows

Standard methods and mechanisms for interoperability, collaboration, and security of data in a Solid Pod must realize these needs, and it must be done without changing the fundamentals of Solid.

Read our stated Problems and Goals for an in-depth understanding of the panel's focus.

Completed Initiatives

Resource Metadata — Resource Metadata was submitted as a candidate proposal to the solid/specification. It was renamed to Auxiliary Resources during Editorial Review.


Solid Data Interoperability Panel meetings are held every other Monday at 12:00 UTC (CG calendar).

This bi-weekly schedule started on April 10th 2023; the latest meeting date can be found via the minutes label or the CG calendar.

Every meeting is also announced on Gitter/Matrix, with a link to its agenda.

Conference call:


Initiative proposals must be submitted as issues, and receive support from members of the panel. At least three panelists (not including the panelist proposing the project) must support creation of the project, with no panel members actively rejecting it. Initiative proposals with support will be prioritized and undertaken by the panel.

Substantive changes submitted to active panel initiatives should be submitted as pull requests, and should receive at least two review approvals from panelists, with no one actively rejecting.

Panel members should work together to settle deadlocks. It may be helpful to request the perspective of a Solid Editor who would ultimately be responsible for accepting submitted candidate proposals to settle deadlocks.
