Description (last modified by curtis)
Bio-Formats needs to be split into two halves: 1) SCIFIO: the core API, metadata handling and standard file format readers; and 2) Bio-Formats: the microscopy file format readers.
The SCIFIO library will be BSD licensed, while Bio-Formats will remain GPL. This architecture will allow SCIFIO to become part of ImageJ2, as well as bundled with non-GPL libraries such as VisAD.

An initial split is committed to the bf-split branch. More work needs to be done to ensure things are working.

Still no time for this yet. Will be needed eventually for ImageJ core I/O though.

Initial version of the split is available in the scifio branch of bio-formats.git. The "scifio" component will be permissively licensed and provide the core I/O infrastructure, while the "bio-formats" component provides the proprietary file format (PFF) readers and is GPL-licensed.
The OME team is planning to discuss the SCIFIO project on next Tuesday, October 25. The plan is to merge the scifio branch onto develop and master after that, then proceed with some major refactoring of the SCIFIO and Bio-Formats projects. But once the initial merge and relicensing is complete, this ticket can be closed.

Yesterday, the scifio branch was merged to develop and then to master. All that remains is to change the copyright blurbs.

Agreeing on the copyright blurb for SCIFIO is taking a very long time to sort out. Unfortunately, this ticket cannot be closed until that is done. Even though the split is done on the technical level, we cannot use SCIFIO as a separate BSD-licensed library in other tools (e.g., VisAD or ITK) until the license is fully sorted out.
For the ImageJ 2.0.0-beta1 release, we will need to add a blurb to the license explaining that while our intention is for the codebase to be BSD-licensed (and ImageJ2 itself is), the entire distribution is technically still a combined work licensed under GPLv2+, because of SCIFIO.

I have submitted a pull request that updates the licenses for all Bio-Formats and SCIFIO components.

- Status changed from accepted to closed
- Resolution set to fixed
The license updates have now been merged to the develop branch.

- Blocking 9 added
(In #9) This ticket is really about improving the infrastructure if I/O for ImageJ2. With SCIFIO, we have now done that. The 2.0.0-beta-7 release is using SCIFIO 0.1.0—File Open and File Save are now extensible—so this ticket is complete.
Remaining tickets about improving the existing I/O mechanism have been migrated to ticket #1920.
