Then why don't you use the same simple scheme with POST? Alternatively, I'd consider using GET and supporting a second form of query with parameters s, p, and o_hash. The first two are like before, the third one is, say, an MD5 hash of the literal (including its datatype or language tag). To reconstruct the right object on the server side, you'd have to do a find(s, p, ANY), calculate the hashes for each result object, and check if one is equal to the given o_hash. This should work with existing triple stores (like RAP's DB model) and should be reasonably fast because no more than a handful of hashes need to be calculated per request. All other solutions I can think of would be a lot more work or much slower.

Hi, I would like to show a given triple on a web page, via an input parameter (GET, POST or SESSION). For example : http://example.org/?triple=jhfff4sd2qd What are the ways to do it ? Are there some best pratices for that ? Reification ? Graphs ? Hashes ? Is there a built in method in RAP ?... Note that I wouldn't use a GET with s, p ,o inside (as RAP web utils) as there will be limits with big literals... Charles Nepote |

Hi, I noticed that some classes are missing from the PHPDoc documentation: OntModel RDFUtil (which is mentioned in the docs for Model::visualize) Various Iterator classes returned from Model, MemModel and DbModel Are they excluded on purpose? I suggest to add them back in. Not having documentation for these classes makes RAP harder to use. You have to read the source to figure out how to use them. Best, Richard |

Hi,
The setBaseURI method of RAP's MemModel and DbModel always appends a
'#' to the base URI (unless the URI already ends in #, :, /, or \).
Why is this? It doesn't seem quite right to me. Base URIs without a
hash at the end are perfectly legal (and more correct, IMO). Adding
the hash gets in the way in some situations, e.g. dealing with
metadata attached to the <> URI, and round-tripping. Also, I think
it's quite reasonable that after executing the following code, $a and
$b should be equal if $a contains a legal base URI:
$model->setBaseURI($a);
$b = $model->getBaseURI();
(And in RAP, $a and $b would often not be equal because of this.)
So, unless I'm missing something important, I suggest to remove this
quirk.
Best,
Richard

Another faceted browsing/search solution you might want to take a look at is the SWED portal [1], it's a web portal that's content is stored as RDF and the code is available, so it's fairly easy to bring in new data sets as the basis of the portal. SIMILE project's longwell is also easily adapted into new datasets. Folks at the W3C semantic-web mailing list[3] would probably be able to give out more pointers.

Hi Charles,
What you're doing looks fine to me. There could be a bug somewhere in
RAP. Can you please give an exact, minimal example that produces the
error? Are you using a DB model directly, or is it wrapped in an
OntModel or InfModel? I'm puzzled because line 524 is in
findFirstMatchingStatement(...), not in find(...). Also, which PHP
version are you using?

You can do this shorter:
function getPrefixFromURI($uri) {
$prefixes = $this->dbModel->getParsedNamespaces();
return @$prefixes[$uri];
}
(Well, this returns null instead of "" if the prefix is not declared,
but I think that's reasonable.)

You're right, it's a common need. The code above is short and self-
explanatory, I think you can use it directly without a custom function.

Richard

Do I misunderstand the "find" method ?

Ok. Thank you Tobias and Richard.
Here is my code which is working well.
function GetPrefixFromURi($uri)
{
$namespaces = $this->dbModel->getParsedNamespaces();
foreach($namespaces as $namespace_URI => $namespace_prefix)
{
if($namespace_URI == $uri)
{
$return = $namespace_prefix;
break;
}
}
if(!isset($return)) $return = "";
return $return;
}
Why not include this function directly in RAP (rewritten)? I think
getting the prefix is a very common need (am I wrong?).

Hi - I'm working with a small, 100% F/OSS online services company that has a contract to create a faceted search facility for non-profit artist communities across the country. For example, if a San Francisco artist was looking for a performance space in Chicago, she could use this to find a performance space seating 500-1000 with sound amplification and other "facets". Data will initially be statically imported from an initial set of 4-6 participating organizations, but is expected to grow to many more feeds - probably via RSS - in the foreseeable future. I've been looking for open source platforms that can provide us the capabilities we're looking for without much luck. We've talked to Siderean who will give us their Seamark server for (nearly) free since we're building for use by non-profits, but I'd really rather not use commercial code if I can help it. (Sticking to open source will enable us to re-use the technology for future projects non-profit and civil advocacy clients.) But I have to say, they have a nice solution. Anyway, I've been looking a bit at RAP, Swish-E, Redland, SIMILE, Sesame, Flamenco and the OAI-PMH initiative, none of which are really aimed at faceted search, though they offer tools to help. I've got some experience with RDF from the P3P and FOAF communities, but I am in no way an expert, and truth be told, I'm a bit at a loss to even understand the architecture of such a search engine. Any insights and/or suggestions will be most welcome. BTW: I also have a small contract available for a month or two part-time work to help with this project. Please do not post this offer elsewhere. Thank you, =Fen -- Fen Labalme Technology Consultant CivicActions, LLC |

Hi Charles, did you see the $model->getParsedNamespaces() method? Returns an associative namespaces from prefixes to namespace URIs. It should do what you want.

Hi, I have a few rdf files I have been working with that declare a set of entities in a dtd, and use these in the rdf content. They are set up like this so that a different dtd file is selected for each language, in the same way that the Mozilla browser provides l10n. Does RAP support automatically replacing the references with the actual val= ues? If I merge the desired dtd file into the rdf, will the parser pick them up? -- John |

Hi,
I am trying to select a set of data out of a Mozilla extension
install.rdf file. I am using SPARQL because it will be easy for
developers to pick up and learn.
My problem is that when an optional entry doesnt exist (iconURL), none
of the fields are returned. This is the query I was trying to
perform.
SELECT ?version, ?name, ?description, ?creator, ?icon
WHERE (?x, <em:version>, ?version),
(?x, <em:name>, ?name),
(?x, <em:description>, ?description),
(?x, <em:creator>, ?creator),
(?x, <em:iconURL>, ?icon)
USING em FOR <http://www.mozilla.org/2004/em-rdf#>
To work around this, I am individually selecting each optional piece
of data. Can this be improved on?
