Any digital project begins with well-defined, and well-formed, digital assets. I found this model and illustration a great example of how and where to begin when undertaking a digitization project.
As explained in the FAQ, “The model shows the logical sequence of receiving, appraising, selecting (or disposing of) data, followed by ingest and subsequent actions such as preservation, storage, access, and possibly transformations or reappraisals of the data. The model allows curators to identify potential weaknesses in policies, or gaps in the archival chain. It also identifies ongoing concerns such as community watch which could be incorporated into working practice, and identifies other stakeholders as sources or users of data, or as people who could pick up the process where your institution’s responsibilities end.”
