Hello! We are currently developing integration service in order to connect it with Nuxeo platform. We are faced with the following problem: it is not clear how to get a list of all metadata for a particular document type (we create custom types), also we can’t find metadata format (e.g. date, dictionary, etc.) and if it is mandatory or not. All we were able to find is that this information is contained in the layouts. How do we get a description of layout? Аre there any other ways to get metadata and the info we want?
