[jira] Issue Comment Edited: (TIKA-482) Refactor image and jpeg
parsers for access to MetadataExtractor API
[ https://issues.apache.org/jira/browse/TIKA-482?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12906370#action_12906370 ]

--------------------------------------------------------------
I see the difference in date now:
assertEquals("Date/Time Original for when the photo was taken, unspecified time zone",
- "2009-08-11T09:09:45", metadata.get(Metadata.DATE));
+ "2009-08-11T09:09:45", metadata.get(Metadata.ORIGINAL_DATE));
assertEquals("This image has different Date/Time than Date/Time Original, so it is probably modification date",
- "2009-10-02T23:02:49", metadata.get(Metadata.LAST_MODIFIED));
+ "2009-10-02T23:02:49", metadata.get(Metadata.DATE));
I don't agree to this change, because the javadocs of DublinCore.DATE say "Typically, Date will be associated with the creation or availability of the resource".

> Key: TIKA-482
> URL: https://issues.apache.org/jira/browse/TIKA-482
> Project: Tika
> Issue Type: Improvement
> Components: parser
> Affects Versions: 0.7
> Reporter: Staffan Olsson
> Attachments: TIKA-451-DublinCore_and_TIKA-482.patch

>
> When I added support for more image metadata in TIKA-472, i realized
> the current design had some restrictions:
> * I could not access the typed getters from Metadata Extractor, such
> as getDate (to format iso date) and getStringArray (for keywords).
> * The handler function was called one field at a time which prevents
> logic where one field depends on the value of another (there is for
> example record versions and fields that specify encoding)
> See attached patch. It refactors TiffExtractor to MetadataExtractorExtractor.
> The patch also includes the date fix, see https://issues.apache.org/jira/browse/TIKA-451#action_12898794
> We can later add more Extractors using other libraries, and map to parsers based on format. For example we already use ImageIO in ImageParser so maybe there should be an ImageIOExtractor.
