Xavier Perseguers updated TIKA-2108:
------------------------------------
Description:
When extracting metadata for a file with categories, the comma (or semi-colon -
according to the IPTC specification) -separated list of categories is extracted
as a blank space-separated list of terms.
Example with https://dl.dropboxusercontent.com/u/3177102/sample.jpg
{code}
java -jar tika-app-1.13.jar --xml sample.jpg | grep Category
<meta name="Supplemental Category(s)" content="Fribourg Cathédrale Pont de la
Poya"/>
{code}
When using exiftool:
{code}
exiftool sample.jpg | grep Categories
Supplemental Categories : Fribourg, Cathédrale, Pont de la Poya
{code}
This is not a problem when using Tika with, say, Solr since stopwords such as
"de" and "la" will be dropped. However, when using Tika standalone with an
external tool, there is no way to fetch the *actual* list of categories, namely:
* Fribourg
* Cathédrale
* Pont de la Poya
where blank spaces in the title may be wanted instead of getting single-term
topic names.
