As we had announced, this week the TLA archive has been migrated to use the CMDI metadata format. If you want to know more about the technical details you can have a look at the CLARIN website.
For our depositors this means that the process of archiving data has changed somewhat. There is a new version of LAMUS that only accepts CMDI. Archiving IMDI metadata is no longer possible and the old LAMUS is no longer available. You can find the manual to the new LAMUS and a short guide listing the differences to the old LAMUS on the LAMUS page. There you can also find a general guide to archiving in the CMDI realm (direct PDF link). If you are using Arbil, you will also need to update your remote locations. The easiest way to do this (if you have the newest Arbil version) is to remove the remote locations and then re-add them.
