Any "optional" fields that are specified when populating the pool must also be specified when retrieving assets from the pool (i.e. they become "mandatory" once they are used for an asset). For example, if the hash value is specified when fetching into the pool, then it must also be specified when attempting to refer to files in the pool. |
Hash algorithms:
sha1 | If a sha1 is available, you can validate the hash as the file is downloaded. If such a hash is available, it should be used. The link and change_hint properties have no effect on the pool file name, so the file is shared even if it is downloaded from different locations. |
besha1 | This algorithm hashes some of the file along with the file size in order to verify the contents. It also moves the link and change_hint properties into the pool filename. |
MD5 | Uses the MD5 hash algorithm to validate files. |
(none) | Without any hash, the file cannot be verified as it is downloaded, and the system will rely on the link and change_hint properties to give the pool a unique filename. |
