in the samples directory there are examples of aaApi_SelectLinkDataByObject which would fill the same table and have the same "Get" functions.
If you use the folder tree structure to identify your projects you could use use aaApi_SelectProjectsFromBranch to get the list of folders in the project, then for each folder use aaApi_SelectDocumentsByProjectId to get the list of documents, then for each document you can run the link data set of things to get the attributes.
Or you could use the Export/Import feature to export a spreadsheet of all the document attributes if that is your sole end goal, then you could use Export/Import to load it back in later if needed.
