Cache/ Save Requests for CODECHECK Venue Types and Names within OJS

[dxL1nus]

Integrate this with the plugin that these requests need to be cached somehow

459    $codecheckVenueTypes = new CodecheckVenueTypes();
460    $codecheckVenueNames = new CodecheckVenueNames();

Check if there is a mechanism in OJS to store this information easily:

• look in PKP forum
• or the plug-in Developer Documentation
• look in source code of plug-ins made by PKP themselves how they internally save their e.g. settings
• e.g., as a JSON object in a hidden property field of the plugin
• or in the OJS database
