EDL: Edit Decision List.

This is a text format list showing the timecode position of the clips that are used in a project. Therefore, all tapes need to have timecode and a unique name like "Atmos of the naked silver chick". The tapes are digitized and edited and the EDL is exported. Exporting the EDL allows any other system, which understands the EDL, to reconstruct the edits. There are some different formats, which covers also fades etc.

OMF: Open Media Framework.

Another format that allows you to export & import projects from / to other systems. You need to create an OMF Composition file, which is close to an EDL and the clips consolidated to a hard drive. There are some websites describing these procedures. Enter "OMF export" into your search engine.

These import export things are very usable but not easy to handle.
