[jira] [Commented] (TIKA-930) Consolidation of Some Tika Core Properties

["Nick Burch (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TIKA-930?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13404869#comment-13404869 ] 

Nick Burch commented on TIKA-930:
---------------------------------

In terms of dcmi, we tend to take a pragmatic view on metadata standards. If it's good enough to be useful, and it won't confuse, use it! Try to keep things simple though, so don't include a whole standard just for the sake of it... But if it provides value then go for it

> There are a few properties in TikaCoreProperties which overlap and I think we should minimize ambiguity by consolidating them into a single composite property with the clearest name, the most general specification referenced as its primary property, and the others and deprecated strings as its secondaries.
> Here's the proposed pseudo-code for the changes:
> Remove TikaCoreProperties.SUBJECT
> TikaCoreProperties.KEYWORDS <- DublinCore.SUBJECT, { Office.KEYWORDS, MSOffice.KEYWORDS, Metadata.SUBJECT }
> Remove TikaCoreProperties.DATE
> TikaCoreProperties.CREATION_DATE <- DublinCore.DATE, { Office.CREATION_DATE, MSOffice.CREATION_DATE, Metadata.DATE }
> Remove TikaCoreProperties.MODIFIED
> TikaCoreProperties.SAVE_DATE <- DublinCore.MODIFIED, { Office.SAVE_DATE, MSOffice.LAST_SAVED, Metadata.MODIFIED, "Last-Modified" }
> and an example of the Java changes:
> {code:title=TikaCoreProperties.java *Before*}
>     /**
>      * @see DublinCore#SUBJECT
>      */
>     public static final Property SUBJECT = Property.composite(DublinCore.SUBJECT, 
>             new Property[] { Property.internalText(Metadata.SUBJECT) });
>       
>     /**
>      * @see Office#KEYWORDS
>      */
>     public static final Property KEYWORDS = Property.composite(Office.KEYWORDS,
>             new Property[] { Property.internalTextBag(MSOffice.KEYWORDS) });
> {code}
> would become
> {code:title= TikaCoreProperties.java *After*}
>     /**
>      * @see DublinCore#SUBJECT
>      * @see Office#KEYWORDS
>      */
>     public static final Property KEYWORDS = Property.composite(DublinCore.SUBJECT,
>             new Property[] { 
>     		    Office.KEYWORDS, 
>     		    Property.internalTextBag(MSOffice.KEYWORDS),
>     		    Property.internalText(Metadata.SUBJECT)
>     		});
> {code}
> Since this would require a bit of refactoring for parsers that use the properties being removed I thought it best to get some feedback before working up a full patch.
> Does this seem like a reasonable approach?
