PSDLA

The Portex Standard Data License Agreement (PSDLA) is an open source data license framework.

Data licensing has become increasingly important in the age of AI. Whether it's protecting valuable IP or structuring exclusive deals to gain an edge, there is a need for clear and modular data licensing standards for both data owners and acquirers. This is where Portex's Standard Data License Agreement (PSLDA) framework fits in.

Inspired by Creative Commons’ “pick-a-badge” simplicity, PSDLA lets buyers and sellers choose a license that matches their commercial goals without re-drafting a full contract each time. You can view the PSDLA framework on GitHub below.

Why use PSDLA?

• Purpose-built for data & AI – Clauses cover model-training rights, derivative-model IP, output indemnification, and more.

• Modular – All versions share a common template covering ethical, practical, and transaction considerations, but feature already-built clauses for common permutations that users can easily select (e.g. exclusive vs. non-exclusive data sales).

• Human-readable & machine-readable – Each license file ships as Markdown and JSON for easy UI integration and API or MCP access.

• Versioned – versioning based on SemVer, e.g. v1.0, v1.1, v2.0, to account for improvements.
