Migrate Metadata into KM

We have a large amount of MS Office documents and PDFs that we are plannning to move into our KM repository. These documents all have metadata stored within the document, i.e. Dublic Core metadata. We want to copy this metadata in the documents to the KM database. For example, we want to copy the Title metadata field of a MS Word document to the Name property of the corresponding document in KM.

Has anyone else done this? Could you recommend how?
