Tim Allison commented on TIKA-1640:
-----------------------------------
Might be useful to add properties, too?
{code:xml}
<aliases>
<metadata key="foo"
aliasInterface="org.apache.tika.metadata.TikaCoreProperties"
aliasProperty="MODIFIED"/>
</aliases>
{code}
Don't know if this adds too much complexity, but it would be nice to encourage
the move away from strings as metadata keys.
If we assume interfaces, something like this could offer a start to this
solution.
{code}
try {
Class tcp =
Class.forName("org.apache.tika.metadata.TikaCoreProperties");
Field field = tcp.getField("COMMENTS");
Object objProp = field.get(null);
if (objProp instanceof Property) {
Property prop = (Property) objProp;
System.out.println("SUCCESS: " + prop.getName());
}
} catch (NoSuchFieldException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
{code}
> Make ExternalParser support aliases for key names in extracted metadata

> Key: TIKA-1640
> URL: https://issues.apache.org/jira/browse/TIKA-1640
> Project: Tika
> Issue Type: Improvement
> Components: parser
> Reporter: Chris A. Mattmann
> Assignee: Tim Allison
> Fix For: 1.9

>
> Over in TIKA-1639, we were discussing the work outside of Tika that [~rgauss]
> did (per [~gagravarr]) on the EXIFTool parsing. I added support in TIKA-1639
> for this, but one thing Ray's code-based work did that my config oriented
> work didn't is allow for renaming extracted metadata key names to better
> support having consistent metadata across parsers.
> Here's one way to do it:
> ExternalParser could have a config section like so:
> {code:xml}
> <aliases>
> <metadata key="foo" alias="bar"/>
> <metadata key="foo2" alias="bar2"/>
> </aliases>
> {code}
> Then this could be used to rename metadata keys.
> I'll implement that in this issue.
