DEVELOPMENT VERSION: This is an experimental DALICC environment. Features, data and APIs may change or be reset without notice. A stable version of this service, with a potentially different feature set, will be made available soon at dalicc.net.

Changes to the license models


What DALICC changed in its curated models, when, and why.

A license model is corrected when a reading of the legal text turns out to be wrong. Every correction changes what the compatibility checker answers, so each change below names the reason behind it and links to the record it was made on.

  • Creative Commons Attribution-ShareAlike 4.0 International version 2 2026-09-24

    added Permission: Charge distribution fee

    Review finding dalicc:chargeDistributionFee was missing, although the other four 4.0 records and all 287 Creative Commons ports of the library carry it, and nothing in this licence limits what the licensee may charge: Section 2(a)(1) grants the rights royalty-free and commercial use is expressly permitted. Section 4 of the legal code, the sui generis database rights section, says nothing about fees either. Added, so that the six records of the 4.0 set model the fee question identically. This was flagged before the review in the review of duplicates (see the review method, docs/LICENSE_REVIEW.md section 3).
