LAMUS2 is a new version of the deposit tool for The Language Archive that differs from its predecessor in a number of ways. Besides some cosmetic differences and some changes in layout, the most important differences are the following:

– LAMUS2 only accepts metadata in the CMDI format, whereas LAMUS1 worked with IMDI metadata. This means that in Arbil (or any other CMDI-capable metadata editor) you will have to create your metadata in CMDI format (see last point about supported profiles). The latest version of Arbil is capable of exporting IMDI metadata as CMDI, should you have any existing IMDI metadata that is not yet in the archive. Upon exporting in Arbil, tick the appropriate option in the export window under “More options”, as described in the manual. Changes to metadata that is already in the archive should be done on a freshly downloaded CMDI copy.

– In LAMUS2, you can no longer create a collection hierarchy (corpus-nodes in IMDI terminology). You will have to create such a structure with a CMDI editor such as Arbil and then upload it in LAMUS2.

– It is no longer possible to modify names of metadata and resources in LAMUS2, so you should name your files properly before uploading them.

– It is no longer possible to edit the name, title and description metadata fields in LAMUS2.

– It is no longer possible to view file content or metadata content in LAMUS2.

– LAMUS2 cannot be used to modify data in parallel corpus structures. You can however remove parallel links and submit a workspace, after which modifying the data will be possible again.

– LAMUS2 has a new feature that allows you to upload data and metadata as a zip file. It will unpack the zip on the server once the upload is finished. If you have uploaded a certain CMDI structure in a zip file, it will remain in tact once extracted. (Note for NBL and LAG departments at MPI: archiving of complete zip files can still be done via the Unlinked_files directory, those will not be unpacked).

– LAMUS2 no longer requires Java to be installed on your computer, just a recent web browser will do.

– In The Language Archive, we will only support a limited number of CMDI profiles. These are currently the following:

– lat-corpus
– lat-session
– collection (CLARIN-recommended)
– VALID
– SL-TLA
– LESSLA
– LUCEA
– Soundbites
– DiscAn profiles
– Bat-image

Note: if you would like to deposit CMDI profiles other than lat-session, lat-corpus or SL-TLA, please let us know, since this will require some configuration changes.
