Ideographic Variation Database

The Ideographic Variation Database provides a registry for collections of unique variation sequences containing unified ideographs, allowing for standardized interchange according to UTS#37, Unicode Ideographic Variation Database.

This page records the successive versions of the IVD, gives the review instructions, and lists the submissions under review (if any).

Versions of the IVD

For each submission which is accepted, a new, cumulative, version of the IVD is created. Versions are identified by the date of their release. Once released, a version is immutable.

The following table lists the successive versions of the IVD:

Version	Change
2007-12-14	Combined registration of the Adobe-Japan1 collection and of sequences in that collection

Review instructions

Reviewers are encouraged to comment on any aspect of the submissions, but more particularly on:

• whether the intent of a proposed collection is appropriately described
• whether the glyphic subset corresponding to a proposed sequence is indeed a glyphic subset of the base character for the sequence
• whether the proposed sequences are congruent with the scope of their collection, or whether a new collection may be more appropriate

All comments should be sent via the reporting form and will be forwarded to the submitter. The content of the submission may be adjusted during the review period to account for the comments received.

Submissions under review

At this point, there are no submissions under review.
