File-related Metadata

Hello,
I'm having an issue where I'm getting back two or three metadata properties
that are related to a temp file that tika is apparently creating under the
hood:
File Modified Date (the current date)
File Name (temp file name: apache-tika-3021300783416279997.tmp)
File Size
I assume this is because I only have a stream to give Tika and no longer
have a physical file.  However the users are seeing these (particularly the
modified date) and misinterpreting it.
I'd like to exclude these, which I could of course do by just a
string-based filter.  However that feels a little hackish... I was hoping
there may be some way to deactivate file metadata if Tika is the one that
created the temp file?  I tried to find the spot in Tika where these are
being added by greping all the source but I seem to have come up empty for
some reason.
Thanks for any pointers,
Brian

So, after some debugging I discovered the root cause.  The image metadata
extractor is producing properties for "file modified date", "file name" and
"file size."
Unfortunately as mentioned in my original post, the file information is at
times misleading since it can reflect a tika temp file.   However I'm not
sure there is a clean or painless way to exclude these from the
ImageMetadataExtractor without basically replacing that parser with a
subclass?
So, the easiest fix might be for me to remove these properties as a post
operation after the metadata is extracted.  Not as clean as I would like
but it should work.
Thanks,
Brian

Hello, If I understand correctly extended attributes are not supported : https://issues.apache.org/jira/browse/HDFS-2006. How would you store small amounts of metadata ("extended attributes") per HDFS file/directory? Anybody has any experience? thanks, Petru
Hello, What is the size of the metadata information if a file occupies a single block (of 64Mb) on HDFS ? Is there any specific formula using which we can calculate the size of the metadata ?
Hi All,  Before I go and wind back my code change to my project.. I though I would throw out to comment..  Requirement: That my Commands into the Processors carry metaData (timestamp, accountId, userId)                       And that my Events carry the same info on the way out. Problem: If I use composition (put the "cmd" in a wrapper command, and the same for the event) I have to
I'm attempting to drop a sharded collection and I keep receiving this error: Wed Oct 26 14:45:46 uncaught exception: drop failed: { "assertion" : "collection's metadata is undergoing changes. Please try again.", "assertionCode" : 13331, "errmsg" : "db assertion failure", "ok" : 0 } I've tried again many times, but with no luck. Any thoughts on debugging this? I'm thinking this may also be
Hi, From a brief review of the different parsers Tika provides, it seems like the parser basically add metadata as the underlying system provides them. It would be great to try and streamline the metadata creation so some will be consistent across parsers. For example, author, title, date (with ISO format). This means, for example, if you create a Lucene Document out of it, then you know what to
Hi there I don't know if this is the right place for a bug report, but I found two bugs in the DatabaseMetaData.getExportedKeys implementation (Both 2 and 3 Beta): Bug 1: It does not return any info about foreign key relationships that involve more than one key, Bug 2: It has incorrect values for the field KEY_SEQ. This should be the sequence number within the foreign key, but the driver

Greetings... Is it possible to access JDBC metadata through iBatis? For example, if I want to check to see if a particular table exists in a database? Thanks in advance! Victor
hi, i'm trying to add Dublingcode metadata to my index, i wrote the plugin as descriped at http://wiki.apache.org/nutch/CreateNewFilter and i build the project using ant... but when crawled my intranet i can't find the DoublingCode metadata in my index ?? did i missunderstand something ? thx _________________________________________________________________ Windows Live helps you keep
hello, I have written a parser and indexer for dublin core metadata. is there anyone who has worked on it and can help me out where i have gone wrong. I have followed the instructions on the write plugin page and written and compiled the following two plugins. ----Indexer------------------------- package org.apache.nutch.parse.dcmeta; import org.apache.commons.logging.Log; import org.apache.commons
