At XLDB 2012 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.
