LAMUS2 (Language Archive Management and Upload System) is developed at the Max Planck Institute for Psycholinguistics, Nijmegen, the Netherlands. It is a web-based application that allows users to organize and update the content of the extensive archive of the CMDI corpus at the MPI.
The application allows researchers to manage their specific part of the archive with as little intervention of corpus- or system managers as possible. Various kinds of resources (e.g. video-, audio data, pictures and annotations) can be linked to the tree structure of the archive, enriching the content of the corpus. LAMUS2 is designed around virtual workspaces, which provide safe working environments for its users. Managing the resources and the structure of the sub-corpus in this workspace will not affect the actual archive itself. Only when the researcher has finished working on the workspace and the data is submitted, will such data be incorporated into the actual archive. After the transfer, search indexes will be updated for the metadata and the content. During the whole process various checks are being performed on the metadata and on the resources to ensure the consistency and the coherence of the archive.
LAMUS2 is visualized through an easy-to-use interface which allow users to:
The main LAMUS2 page can be accessed by going to http://corpus1.mpi.nl/jkc/lamus/ in a recent web browser. On top of the page, you will find the various functions and buttons you can use with Lamus2, the bottom half of the screen contains a nested dialog, which at times will display workspace and file-related information.
LAMUS2 is a new version of the deposit tool for The Language Archive that differs from its predecessor in a number of ways. The most important changes are:
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.
