Acceptable Practice
|
Best Practice is the same as the Archival Cluster for all material types | Discipline specific file formats (ex. FITS) are acceptable as long as they bring added value to the file. Unless noted all deliverables are 4x5 @ 72 ppi & JPEG1 | All thumbnails are 150 pixels in the greater dimension @ 72 ppi & JPEG | ||
| Archival files should confirm to any of the following formats. “Best Practice” required for computing or library projects. | Minimum required elements for inclusion in the DDL. Default to Best Practice unless otherwise noted. | |||||
