What you can do with DALICC

Search


The library holds the licenses DALICC knows, each one written out as machine readable rules. Search it by name here, or answer a questionnaire about what you want to allow and let the License Search narrow it down.

Compose


The composer builds a license out of the permissions, prohibitions and duties you switch on. It reasons over the result before you publish it, so a license that contradicts itself is caught while you are still writing it.

Combine


Put several licenses into one bundle and the checker says whether they can be used together. It names every conflict it finds and, with a target license, whether the bundle may be released under that one.

Compare


Pick two or more licenses and the comparator puts their rules side by side. The matrix shows where they agree and where one permits what another forbids.

Check


Name a public repository and the checker reads the licenses of its dependencies. It maps them onto DALICC records and reports the conflicts between them, and the conflicts with a target license when you name one.

Reason


A dependency graph states how the named actions relate to one another, and every check follows one. Read the core graphs in the viewer, or build a graph of your own in the editor and check against that.

With an account you draft and publish licenses under your own name, keep dependency graphs of your own and call the API with a token. Accounts are given by invitation; the license pages say what each one does without one.

DALICC in numbers


290 Licenses in the library

289 Jurisdiction ports of them

142 Terms in the DALICC vocabulary

A jurisdiction port is the same license adapted to another legal system. DALICC keeps every one of them, with its own address, and groups it under the license it came from.
