Metadata changes in 4.x
In general, we're trying to ensure that we prefix all "user generated" metadata keys. There could be surprises if files overwrote existing metadata keys, like "Content-Type". The overarching issue tracking this is:
| Jira | ||||||
|---|---|---|---|---|---|---|
|
- HTML custom metadata keys are now prefixed with "html:" (TIKA-4357)
- MAPI metadata prefix has changed to "mapi:" (TIKA-4360) and "mapi" has been removed from the key names.
- "resourceName" has changed to "X-TIKA:resourceName" (side effect on TIKA-4410).
- Unrecognized image metadata keys are now prefixed with "img:" (TIKA-4426).
Other metadata changes:
- Office metadata prefix has changed from "meta" to "office" (TIKA-???).
