Public, private and free data

The experimental data on OCHEM has three access levels:

The difference between public and free data is in the fact that OCHEM limits the export of sensitive information (in particular, molecular structures) for non-free data. Different categories of users can have individual limits for exporting non-free data.

Users can make their data public or free any time using the Compound property browser as shown on the screenshot below.

The access levels cannot be easily reduced. Once the data is free, you cannot make it non-downloadable or private.

Approved data

The data published by users (public and free data as described above) can be tagged as "approved" by OCHEM moderators.

By default, users see only the approved data published by other users. However, there is an option to show all public data, including the records not yet approved by moderators.
