Add namespaces to our metadata keys
-----------------------------------
Key: TIKA-61
URL: https://issues.apache.org/jira/browse/TIKA-61
Project: Tika
Issue Type: Improvement
Reporter: Bertrand Delacretaz
Priority: Minor
To avoid collisions, we should namespace our metadata keys, using something like
// a) Set Dublin Core title
metadata.set("http://purl.org/dc/elements/1.1/";, "title", title);
// b) Set OpenDocument keywords
metadata.set(
"urn:oasis:names:tc:opendocument:xmlns:meta:1.0",
"keywords", keywords);
Or also using the namespace prefix in the name:
// c)
metadata.set(
"urn:oasis:names:tc:opendocument:xmlns:meta:1.0",
"dc:keywords", keywords);
not sure what the implications of c) are. If the key is composed of the
namespace URL and item name we should be fine, so for case a) I'd use
http://purl.org/dc/elements/1.1/#title
for the key, and escape # if it is used in either the namespace URL or item
name.
