Terms: Representation Forms
The different forms a representation can be
Values | Description |
---|---|
Original | Original format, bit-per-bit preserved. The format can be obsolete (Word Perfect 1.0) and very difficult to read (i.e. MJP2K). |
Preservation | Format which will have long term support (i.e. PDF 1A) |
Access | Form which is ready for direct dissemination by having an universally accepted format (e.g. H264 video) in a decent but manageable quality (i.e. 520p MP4/H264 video) versus a 30000x30000 pixel image (unusable for access because it would crash most browsers). |
Physical | Represents an object in the physical world. This object is metadata only. |
