 ==== How do I remove datasets? ====
-FIXME
+The best solution is to use the administration interface (require login and appropriate user rights) and the "Dataset manager". Within this interface datasets can be deactivated. they will still be in the database, but will be invisible. Sometimes conflicts between datasets may arise (due to naming conventions) which may require a full reinitialisation of the database. If a dataset is to be permanently removed, remove the XML and XMD files from the webrun directory and follow the steps under [[#How do I reinitialise the database?]]. This require access to the webrun directory at the server running METAMOD.
 ==== How do I change metadata? ====
-FIXME
+The preferred solution is to use the metadata editor included in the software. This is launched using the "File upload" menu and the option "Dataset administration". Login and appropriate privileges are required.
+Sometimes, the solution above is insufficient. Under such conditions, direct modification of metadata and import of these from the webrun directory using ''import_datasets'' may be an option. This option should be used with care!
+==== How do I reinitialise the database? ====
+Use the following recipe (information in <> to be substituted as appropriate):
+  - sudo /etc/init.d/metamodServices-<implementation> stop
+  - sudo /etc/init.d/catalyst-<implementation> stop
+  - sudo -u <web server owner> <implementation directory>/base/init/create_and_load_all.sh <configuration directory>
+  - sudo /etc/init.d/metamodServices-<implementation> start
+  - sudo /etc/init.d/catalyst-<implementation> start

+==== File formats relevance for METAMOD ====
+METAMOD is essentially agnostic concerning file formats. However, [[#NetCDF/CF|as mentioned below]], METAMOD has extended support for data uploaded as NetCDF/CF following the requirements of METAMOD.
+Basically METAMOD can relate to any file as long as the metadata are created manually and uploaded, but metadata can be extracted automatically from NetCDF/CF files.
