License Composer

The license composer allows you to create your own license. Just go through the form below and specify your license terms.

DALICC checks licenses against their models and does not replace legal advice. For a decision that matters, ask a lawyer.

Already have the text of a license? Text-to-License reads it and fills in this form for you; you review the proposal before anything is saved. It is available to people with a DALICC account, so please log in to use it.

How do you want to state your terms?

The questions offer one switch per action, with the duties DALICC knows for it. The expert view shows every statement of your license as a row, so you can add a permission, a prohibition or a duty for any term of the vocabulary and hang a duty on any permission. Both views hold the same license, and switching keeps it.

Fills this form in from a curated record, so you can change what you need and publish your own variant. The name is left empty for you to fill in, and everything you have typed here so far is replaced. A DALICC identifier (for example Apache-2.0) works too.

Fills this form in from a model you downloaded here before, as Turtle, JSON-LD or RDF/XML (up to 2 MB), title included. Everything you have typed here so far is replaced. The file is read and forgotten: nothing is stored.

Disclaimer
License text

DALICC can write the license text from the form above, in plain English. The text is a draft made from your model, not the license itself: read it, change what you want changed, and check it before you publish it as part of your license. What is sent to the provider is the model, never the names you entered, and writing a text publishes nothing. The model is sent to: groq API.

Writing the text is available to people with a DALICC account, so please log in to use it. You can still type or paste a text into the field yourself.

Up to 60,000 characters. Stored with the license as dalicc:licenseText, and left out when it is empty.

For a license of the library or a model you have on disk, License-to-Text writes the text on a page of its own.

My resulting license

Here you can find the human-readable and machine-readable version of the license you created. You can download both, and bookmark the license in this browser.

Summary

Fill in the form above; a summary of your license terms appears here.

Consistency

Press "Check consistency" and DALICC reasons over the dependency graph, reporting contradicting statements before anything is published.

The consistency check reasons with this graph: it decides which of your terms contradict each other; how the check uses this graph. A core graph is curated by the project. While you are signed in, your own graphs and the ones shared with you appear here too, drafts included.

Publishing mints a permanent DALICC URI for your license. It is unlisted: keep the address, it is the only way back to it. Nothing is written before you press Publish.
