WooCommerce Plugin to convert local attributes into global attributes

Hello, We currently have the problem that the JTL Connector syncs our products from the merchandise management software JTL Wawi into WooCommerce and then also provides them with attributes in WooCommerce. These attributes are stored in local attributes, which means that you cannot filter them. We need a plugin for Wordpress that turns the local attributes into global ones and assigns the values to the products. This means: 1. product sync from JTL to Woocommerce. 2. (here the function of the plugin starts) The plugin scans all products for local attributes. 3. If an attribute already exists as a global attribute, check if the key of the local attribute already exists in the global attribute, if not create it. If the attribute does not yet exist, create it including the first key. 4. Assign the existing or newly created global attribute to the product and remove the local attribute from the product. This workflow should be started immediately after the JTL Connector finished syncing (perhaps after a short period of time not receiving data). The JTL Connector source can be found here: [login to view URL] You !should not! edit the connector. We do need an additional plugin, which may be implemented in the connector. Edited 210225: A. The JTL-Connector (Wordpress-Plugin) !shall not! be edited to keep the changes update-proof. B. There is a documentation for JTL-Connector available. [login to view URL] Changes to the behaviour of the JTL-Connector must be done by using "events" of the JTL-Connector. [login to view URL] C. Changes (item 2. to 4., see above) shall be made by adding a internal "plugin" to the event-structure of JTL-Connector (Wordpress-Plugin). If this should not work (it should work, but you never know...), the employer shall be contacted to discuss the creation of an independent Wordpress-Plugin, which fulfills the described features of item 2. to 4.
