HDF parsing using Apache Tika

Question

How to parse HDF files(.h5) using Apache Tika.

Apache Tika provides parser for .h5 files, but Using that I'm not able to parse the data.

Parser parser=new HDFParser();
Metadata metadata=new Metadata();
ContentHandler handler=new BodyContentHandler();
FileInputStream fileInputStream=new FileInputStream(path+h5File);

parser.parse(fileInputStream,handler,metadata,new ParseContext());

I can see metadata of file, but I can't get content using handler.

If anyone has done this, Please help me through this.

I have a feeling that the HDF parser is metadata-only, but that it should be pulling out most of the file as metadata. What are you expecting to see but aren't finding in metadata? — Gagravarr, Apr 13 '17 at 14:40
I have converted a video to .h5. I need the 3-D matrix data, which I can see in HDFView. RGB matrix. — ketankk, Apr 15 '17 at 06:56

Simply you can't for the nature of HDF format file.

You have to use metadata.get(field-name-in-string-format); for retrieving information you want.

Alternatively you can try directly this Java library: NetCDF (which it is used, under the hood, by Tika)
