At XLDB 2012 on Wednesday we announced that two major databases that support arrays as first-class objects (MonetDB SciQL and SciDB) have formed a working group in conjunction with XLDB. This working group is proposing a common syntax (provisionally named “ArrayQL”) for manipulating arrays, including array creation and query. In addition, we are working with a third major array-supporting implementation (Rasdaman) to propose an algebra for common array operations.
A common algebra and syntax are expected to benefit array users in the same way that the relational algebra and SQL benefit relational users. The working group is requesting comments on the current documents (which are drafts and unpublished works-in-progress) and would welcome additional members who demonstrate serious interest in this area. Comments may be posted here or sent to firstname.lastname@example.org.
