Hi, METS 1.7 is available at http://www.loc.gov/standards/mets/version17/mets.v1-7.xsd It will replace http://www.loc.gov/standards/mets/mets.xsd in a month if no problems are found. Change requests for the next version of METS are being collected here http://www.socialtext.net/mim-2006/index.cgi?mets_1_8_change_requests METS 1.7 changes: Imports xlink from http://www.loc.gov/standards/xlink/xlink.xsd rather than http://www.loc.gov/standards/mets/xlink.xsd to harmonize with MODS and EAD. Created parType complex type to allow a seq to contain a par. http://www.socialtext.net/mim-2006/index.cgi?cr_1_7_seq_par_and_area_in_ structmap Created a FILECORE attribute group with MIMETYPE, SIZE, CHECKSUM, CHECKSUMTYPE, CREATED; added to mdType and mdRef so they get the core file attributes http://www.socialtext.net/mim-2006/index.cgi?cr_1_7_add_checksum_support _for_metadata Added PREMIS:OBJECT PREMIS:AGENT PREMIS:RIGHTS PREMIS:EVENT to MDTYPE value enumeration http://www.socialtext.net/mim-2006/index.cgi?cr_1_7_add_mdtype_values_fo r_specific_premis_schemas I have checked the new schema against all the example METS in the registered METS profiles and all the samples validate using the 1.7 schema. -- Brian
