Script to update metadata

[fisketjon]

I have an access database with titles/description for 5000+ of my photos. 
Is there a way to use this (or an excel file) to update the title/description metadata tags?

Sure. Export to CSV and use the Import CSV Files feature. This is the fastest way, if your data is compatible with CSV (e.g. no embedded line breaks).

If you can program, you can write a script in PowerShell, Python, Basic, C#, Go, whatever that pulls the data from your Access database via ADO or ODBC and uses the REST API provided by IMWS in IMatch to store the data in the database.
