 These files are created by extracting metadata from netCDF files like name1_xxx.nc, name1_yyy.nc etc. The xml/xmd files on the highest level will remain exactly as they are today. The xml/xmd files on the lowest level will each represent one netCDF file only. The format of these files will be the same as those describing the directory level datasets. (This format is described on [[xml-format]]).
+The dataset ID field (xpath in .xmd file: ''dataset/info@name'') will be now restricted to match one or
+two ''/'' characters, one ''/'' meaning parent (''APPLICATION/DIRECTORY''), two ''/'' meaning file (''APPLICATION/DIRECTORY/FILE'').
+=== Updating from Metamod 2.1 to Metamod 2.2 (adding file-metadata) ===
+The current trunk of Metamod, which will lead to Metamod 2.2, extracts now both levels of metadata
+from fresh uploaded files. The file-metadata from older netcdf-files stored on the same machine in an OpENDAP enabled catalogue can be generated using the program ''createChildDatasets.pl'', which is installed in the script directory and should be used as:
+  createChildDatasets.pl /outputdir
+The outputdir will contain all second level metadata. After manual verification it should be copied over
+to metadata-directory of the project.
