Support for custom metadata writing



We are considering of using (and purchasing) the Metadata library and have some questions about it. We will appreciate the answers.

We want to add our custom metadata to a document in format key/value. We know that Office Open XML supports it and so does pdf. We hoped that your solution will bring that feature for more formats, but after testing the solution, it seems that only the mentioned formats are supported.

We saw list of supported formats, but it is not clear which formats supports custom metadata and which ones not. Is there any such documentation available?

Do you consider to add such support for CAD formats like .dwg, .dxf? Do you have any public (or shareable) roadmap for it?



Yes, at the moment, the custom metadata is supported for Word Processing documents, Presentations, Spreadsheets, and the PDF documents. To check if the custom metadata is supported or not, please visit the Features Overview article in the documentation. For example, to check which document formats support custom metadata, go to Features for Documents article and see Add Key/Value Metadata feature in the table.

I am afraid that we don’t have any public roadmap for such features. However, we have logged it as a new feature request in our Issue Tracking System (ID: METADATANET-3053). We shall check the feasibility of custom metadata in CAD formats and get back to you with further updates.


Hello @usman.aziz,
that’s a shame but thank you for the quick reply and logging my questions as feature request.



You’re welcome.
