Ryan,

Thanks for responding so quickly. On the one hand I'm delighted that you
were unable to reproduce my results. This means I'm not crazy and that
both files are 'valid' RDF (apart from the abuse of dublin core). On the
other hand, it means that my Piggy-Bank is broken somehow. :-(

I can't help thinking the problem is related to my earlier query of Mon,
20 Feb "bibtex2rdf and PB questions." As stated there, I'm using a
recently updated iBook (G4 OS 10.4.3) with the new version of FF
(Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8.0.1)
Gecko/20060111 Firefox/1.5.0.1) and the new version of PB (2.1.1). The
console output from that error is appended to that message. I still have
no satisfactory explanation for that problem. With respect to the current
problem

When I point PB at the first file "copticJohn.rdf":

<?xml version="1.0" encoding="ISO-8859-1"?>

The response from the java console is as follows:

Not very informative is it? When parsing the second file
(copticJohn1.rdf):

I get the expected result and the response from the console is merely:

11:34:36.400 [...orpus.Corpus] Warning: Internal error:
java.io.FileNotFoundException: /Users/jjc/Library/Application
Support/Firefox/Profiles/nel8zymd.default/piggy-bank/temporary-sources/model1141413391181/database/namespaces.dat

(No such file or directory) (3ms)

As to the javascript console, I get the following errors whenever I start
FF regardless of what PB is doing:

Error: Warning: unrecognized command line flag -psn_0_29360129
Source File:

Source File:
http://www.google.com/firefox?client=firefox-a&rls=org.mozilla:en-US:official
Line: 4

I get no further errors, warnings or messages from the javascript console
when PB attemts to parse these two files.

It is also the case that when I use the same version of PB on a windowsXP
box, both files are parsed successfully. It's clear that there is
something wrong with my installation of PB, or FF, or both on my iBook. If
my experimentation is going to continue, I guess I'm going to have to
grasp the nettle firmly and use subversion to download and build the most
recent version of PB. I hope you won't mind further naive questions on
that score as well.

If the console reports included above do give you any inkling as to what
the problem is, please let me know.

Many thanks, and the usual kudos to the assembled wise heads.

Jon
