Need suggestion on file type .HFA to be added Tika.
Hi All,
Identified (Hierarchical File Architecture) HFA file format which is not
presently being identified through Tika.
file format details :
extension : *.hfa
Header tag contains string EHFA_HEADER_TAG
Links :
1.
ftp://ftp.ecn.purdue.edu/jshan/86/help/html/appendices/hfa_object_directory.htm
2. ftp://ftp.ecn.purdue.edu/jshan/86/help/html/appendices/Ehfa_HeaderTag.htm
Should this be considered as custom mime type or standard mime type. ?
Need suggestion for content type(mime-type type) of this file format.
.
Regards
Nandan Padar Chandrashekar

Looks fine for adding to Tika to me

As it's a common well known file type, it should be a standard one. It'd
really only need to be a custom one if it was only used in your lab /
school / company and no-where else

application/x-erdas-hfa seems to be used in at least some places online,
so I'd suggest using that, at least for now
