The 3rd step is only needed if you want to use the auto detect parser. If
you figure out the correct parser a different way, it isn't needed
It sounds like a very helpful short document though. The wiki is at
http://wiki.apache.org/tika/ if you fancy writing it up :)

Thanks Nick and thanks Arturo, for the offer to write a small guide to getting started with parsing. It might be good to create a JIRA issue for this? Arturo, can you head over to JIRA and create an issue to contribute a "get Tika parsing up and running in 5 minutes" quick start guide? Then, you could write the guide in APT format (see here [1] for an example and [2] for more detailed information), add your new guide file to your local SVN checkout, create a patch and then attach it to your new issue.

You have to explicitly tell the AutoDetectParser to try your parser, in
addition to the mime type definition
List your new parser in:
tika-parsers/src/main/resources/META-INF/services/org.apache.tika.parser.Parser
and I think it should then be picked up

Yes, sure.

Is the mime type being detected appropriately? You can check this by putting a println right before getParser in the parse(...) method:

Yes I declared this MIME type in my parser. But the
/getSupportedTypes(context)/ function is never called.
I uploaded a file with the Tika source code that includes my modified
/tika-mimetypes.xml/ file and my new parser /GeoParser.java/. Perhaps
one of you will try it and find out where I'm wrong.

Re: Getting started
Posted by "Mattmann, Chris A (388J)" <ch...@jpl.nasa.gov>.
Hi Arturo,
How exactly are you calling your parser? Are you using the AutoDetectParser? If so, can you put some print statements in in the public void parse(...) method of CompositeParser? Specifically, add a line right after:
Parser parser = getParser(metadata);
// print out the returned parser
System.out.println("Parser returned is: ["+parser.getClass().getName()+"]");
What does that return? Also, have you done the work to map your incoming document type in the tika-mimetypes.xml file? That is, if you're using AutoDetectParser or anything that extends CompositeParser, the mime type of the incoming document is used to determine what parser gets called? Is the mime type being detected appropriately? You can check this by putting a println right before getParser in the parse(...) method:
// print the mime type
System.out.println("The MIME type is: ["+ metadata.get(Metadata.CONTENT_TYPE)+"]);
Parser parser = getParser(metadata);
What does that print out?
Finally if both of these printlns check out, you should check and make sure that your new parser is correctly mapped to the media type it supports, in other words what Ken said below. Does your parser declare that it supports your expected MIME type?
Let me know and thanks!
Cheers,
Chris

Hi,
I'm still with the same problem.
I think it's all good, I do the/ "mvn install/" and my new class is
included in the generated JAR, but never called.
It should be very simple. I feel a little silly. I don't know how to
make my new parser is found by Tika.
Thanks in advance

Are you sure your new parser is on the classpath?
E.g. put a break on getSupportedTypes() and make sure that's getting
called - if not, then the parser isn't being "found" by Tika.

Hi Ken,
First of all, thanks for your quick response.
This's exactly what I'm doing, but despite that Tika recognizes the new
MIME tipe, my new parser is not called.
I added to tika-mimetypes.xml:
<mime-type type="application/shp">
<!--sub-class-of type="application/octet-stream"/-->
<glob pattern="*.shp"/>
</mime-type>
I created a new class GeoParser:
public class GeoParser implements Parser {
private static final Set<MediaType> SUPPORTED_TYPES =
Collections.singleton(MediaType.application("shp"));
public static final String SHP_MIME_TYPE = "application/shp";
public Set<MediaType> getSupportedTypes(ParseContext context) {
return SUPPORTED_TYPES;
}
public void parse(
InputStream stream, ContentHandler handler,
Metadata metadata, ParseContext context)
throws IOException, SAXException, TikaException {
metadata.set(Metadata.CONTENT_TYPE, SHP_MIME_TYPE);
metadata.set("Hello", "World");
System.out.println("HELLO WORLD");
System.err.println("ERR Hello world");
XHTMLContentHandler xhtml = new XHTMLContentHandler(handler,
metadata);
xhtml.startDocument();
xhtml.endDocument();
}
...
}
And that's the result:
Content-Length: 755072
Content-Type: application/shp
resourceName: comarques250.shp
I don't know wht exactly is failing, but I can't make it work.
Greetings and thanks in advance for your help.

You first need to modify tika-core/src/main/resources/tika-
mimetypes.xml.
E.g. something like this was done for mailbox files.
<mime-type type="application/mbox">
<sub-class-of type="text/plain"/>
<glob pattern="*.mbox"/>
</mime-type>
That maps the suffix to the mime-type.
Then you define the SUPPORTED_TYPES static class field in your parser
class that defines what mime-types it supports.
E.g. for MboxParser:
public class MboxParser implements Parser {
private static final Set<MediaType> SUPPORTED_TYPES =
Collections.singleton(MediaType.application("mbox"));

Hi all,
Some of you already know that I'm working on a new parser
(https://issues.apache.org/jira/browse/TIKA-443). After all day trying
to set up a workspace for Eclipse, I implemented the typical "hello
world" class, in the Tika Parser version. My problem now, is how to
configure Tika in order to call my new parser when a file with especific
extension (p.e. *.shp) is found. I read something about a configuration
file (tika-config.xml) but I couldn't find it in the source code.
Greetings and thanks in advance
Arturo
