Luke sh updated TIKA-1561:
--------------------------
Description:
cited from the http://gcmd.nasa.gov/add/difguide/WRITEADIF.pdf
"The Directory Interchange Format (DIF) is metadata format used to create
directory entries that describe scientific data
sets. A DIF holds a collection of fields, which detail specific information
about the data."
The .dif file respect proper xml format that describe the scientific data set,
the schema xsd files can be found inside the .dif xml file.
i,e, http://gcmd.gsfc.nasa.gov/Aboutus/xml/dif/dif_v9.8.4.xsd
The reason opening this ticket is tika parser for this dif file is being under
consideration with development, the support to identify the file is needed.
Although dif file in this case seems to be an xml file which can be parsed
properly by xmlparser, still it might need a specific process on some of the
fields to be extracted and injected into the System for analysis.
Then it is proposed that the following type 'text/dif+xml' is appended in the
tika-mimetypes.xml that extends the application/xml, so that some special
process can be applied to this particular xml file.
<mime-type type="text/dif+xml">
<root-XML localName="DIF"/>
<root-XML localName="DIF"
namespaceURI="http://gcmd.gsfc.nasa.gov/Aboutus/xml/dif/"/>
<glob pattern="*.dif"/>
<sub-class-of type="application/xml"/>
</mime-type>
Expected MIME type: text/dif+xml
The following is the link to the dif format guide
http://gcmd.nasa.gov/add/difguide/
example dif files:
1) https://www.aoncadis.org/dataset/id/005f3222-7548-11e2-851e-00c0f03d5b7c.dif
2) https://www.aoncadis.org/dataset/id/0091cf0c-7ad3-11e2-851e-00c0f03d5b7c.dif
