Bulk import

Post by james »

I have seen several threads about importing but no definitive answer or example scripts.

I have several thousand documents I would like to import with the details stored in a spreadsheet. I can happily morph this into a particular format and can add the document filename (once scanned). What is the best way to import this and is there a recommended batch size?

I bought the book, but it's not covered in there either.

Good advice always welcome

we have been developing an import app that has drivers for different sources (like CS) and online/cloud providers.

But it missed the inclusion deadline for version 4.0. Hopefully it will be included in version 4.1

Hi James,

I did this before with 10000 documents: viewtopic.php?f=7&t=3133

If you have in your spreadsheet a direct link to unique filenames you can use the following approach. Its not perfect but I got my metadata in:
  1. Create a staging_folder next to your watch_folder and copy all your documents in there
  2. Change ownership of all documents to mayan:mayan
  3. Move all files at ones to your watch_folder
  4. Wait till all documents are loaded (e.g. no documents are left in the watch folder) Sometimes it can hang on documents, move them out of the watch_folder and deal with them seperatly.
  5. Create metadata for each row of your spreadsheet you like to have in mayan
  6. Upload your spreadsheet in a table [spreadsheet_metadata here]
  7. You need to figure out which number correspond to which metadata (SELECT * FROM public.metadata_metadatatype)
    • (If your fields are longer than 255 characters change the 'value' field in metadata_documentmetadata to text)
  8. Per metadata I run the following script to attach the metadata to the documents:

Code: Select all

INSERT INTO metadata_documentmetadata
	SELECT meta.author,doc.id,3
	FROM public.documents_document doc
	inner join spreadsheet_metadata meta on doc.meta::text = meta.reference
	where meta.author IS NOT NULL
ON CONFLICT (document_id, metadata_type_id) DO NOTHING
So in the above command I am adding all author metadata from the spreadsheet to the metadata_type_id field 3 (which is the author). I am sure it would be possible to do this in one go.
