Make commands¶

Several commands are available to help manage your instance. These commands are available through make when launched from the same directory as the Makefile. (If you are running Askomics in a docker container, you will need to connect to it to launch these commands)

You can run the make help command to get a list of available admin commands.

Updating namespaces¶

Version 4.2 added the /data/<uri> route showing the properties linked to a node. To make sure that your URIs are properly redirecting to this route, you should make sure that the namespace_data and namespace_internal configuration option are set to your instance url. Make sure to match either http or https depending on your instance, and don't forget /data/ or /internal/.

Updating an existing instance¶

If you changed the namespaces after having already integrated some files, you will need to run two additional commands to update your existing data.

• make update-base-url You will be prompted to enter the previous namespace url, and then the new one. You can either enter a partial namespace url (ex: http://askomics.org/) or the full one (ex: http://askomics.org/data/) In the latter case, you will need to run the command twice (once for each namespace)

• make clear-cache This will clear the abstraction cache, making sure your data is synchronized with the new namespaces.

Single tenant mode¶

Starting from release 4.4, the Single tenant mode is available through a configuration option. In Virtuoso, aggregating multiples graphs (using several FROM clauses) can be very costly for big/numerous graphs.

Single tenant mode send all queries on all stored graphs, thus speeding up the queries. This means that all graphs are public, and can be queried by any user. This affect starting points, abstractions, and query.

Administrator panel¶

Administrators have access to a specific panel in AskOmics. This Admin tab can be found after clicking on Your Name ▾.

User management¶

From the Admin tab, administrators are able to:

• Create a new user account
• Manage existing user accounts
  • Blocking an user account
  • Setting an user as an administrator
  • Updating an user's individual storage quota
  • Deleting an user

They will also be able to check the last time of activity of an user.

Files¶

A list of all uploaded files is available. Administrators can delete a file at any time.

Datasets¶

All currently stored datasets are available. Administrators can publish, unpublish, and delete them.

Forms / Templates¶

A list of public forms and templates is available. Administator can unpublish them if need be.

Anonymous query¶

Starting from release 4.5, the Anonymous query mode is available through a configuration option. This option allows anonymous users to create full queries (not only previews), and access the results/sparql console associated.

To avoid overloading the server, anonymous queries are regularly deleted. (Every hour for failed queries, and every X days for successful jobs, as defined by the anonymous_query_cleanup variable (default 60)).
