Subject: Storage of UBL documents - ID's
Hello ! Looking at the data model there is frequent use of UUID such as DocumentID . But these seem to be created by the producer not the recipient. Also they don't have any place for a local storage key. That makes sense as the UBL documents are designed to be the communication between partners not the storage model.
Any suggestions on mapping key fields from these documents to a document management system ? The systems I am thinking of using would use a "URL" or "path" .. for example Amazon S3 uses a bucket + path to identify a document, but itself is not searchable. If I were to use such a key-value store for documents which field (if
any) should I use to create the path ? the document UUID ? Also this seems to imply that in such a system I might want (or need) a metadata store as well to map important fields from a document to the actual document store. This would let one search for
documents based on things other than the primary key. If I create a document .. .there is no indication I can find in the spec of the format for document ID's (UUID's), but the samples look like traditional GUID .. Is there a convention for generating UUID's or is this entirely up to the producer ? Any ideas or descriptions of what was successfully used in practice welcome !
