Message-ID: <e82aac7b0801010215w2316bc9fi121cb4390a632827@mail.gmail.com>

Hi,
I'm currently building a search page for computer games and have come across
some teething problems whilst using freebase.

$q = array(
"type" => "/cvg/cvg_platform",
"name" => "Xbox 360",
"games_on_this_platform" => array("game" => array("name" => null))
);

This is the query I based that on from within the freebase query builder:

[{

"type":"/cvg/cvg_platform",

"games_on_this_platform":[{ "game":[{ "name":null }] }],

"name":"Xbox 360"

}]


My PHP script is fairly simple, but it throws up an error "*Warning*:
Invalid argument supplied for foreach()", but this only happens on this
query. I have other queries I have tested like being able to search for a
particular game and that works fine. PHP script below:

<?php

require("metaweb.class.php");
$count = 0;
$results = array();
$mw = new Metaweb();

$q = array(
"type" => "/cvg/cvg_platform",
"name" => "Xbox 360",
"games_on_this_platform" => array("game" => array("name" => null))
);

$auth = 'XXXXXXXXXX';

$results = $mw->read($q, $auth);
$count = count($results);

?>

<?php foreach ($results as $game) : ?>
     <li><?=$game['name']?>
(<?=$game['games_on_this_platform']['game']['name']?>)</li>
<?php endforeach; ?>

Any ideas as to why I get results in the query builder but not in PHP,
seeing as the query is the same?

I've also mentioned this in the discussions board on freebase but I think it
would be good if freebase pages had a link to the MQL query that was used to
generate the data on that particular page. For example, this page (
http://www.freebase.com/view/reorder/topic/en/xbox_360?propertyId=%2Fcvg%2Fcvg_platform%2Fgames_on_this_platform)
does pretty much what I want to do, but has some missing fields etc. It
would be good for developers to be able to quickly see how that was
generated and would shorten the learning curve dramatically.

Thanks,
Chris

Cool news, Chris.  Thanks for sharing it.  One comment here:

It?s not a bug in your code; it?s because not all albums have English titles.  When you ask for

  "name":null

on a topic, you are asking for the name in the default language (English).  Since many of the albums we imported do not have titles that would be useful to an English speaker (all kanji or Cyrillic characters, for example), we didn?t give them English titles.  You can ask for

  "name":[{"value":null,"lang":null}]

instead, or just be prepared for null names in your code.  See <URL: http://blog.freebase.com/?p=58 > for more details on internationalization in Freebase.

Happy new year, Chris.  The problem with using foreach on the result of that query is that it returns a single thing: the platform called ?Xbox 360.?  Now, it has a number of games on that platform, but the root of the query is just the platform itself.

You can turn the query inside-out, to find games whose platform is the Xbox 360, or you can iterate over the games on that platform, instead of iterating over the platform itself.

Gmail never shows you the list-sent copy of a post you sent to a list.  If you 
look at the thread that the message is in, it will show you the one that you 
sent, rather than the one that came back, missing all the list-added headers.

Personally, I think that's a very stupid decision on Google's part, but they 
don't seem willing to change it.

This should probably be in a FAQ somewhere because it seems like it gets asked 
on *some* mailing list I'm on about once a week.

Hi Indy,

 

I'm not a sure what the problem is, but from the error message I'm
guessing that you are specifying an invalid URL. The upload will fail if
the URL is not accessible by the content server. I guess the correct URL
is something like:

Hrm, I never noticed this behaviour until right now, but even so, it would
seem that it did not follow normal behaviour - I didn't get any posts with
the previous message, either mine or from the list.  Ah well, I'll chuck it
up as a sacrifice to Mercury, the messenger god.

Thanks.

Hey Arthur, thanks for looking at this.  The file I'm trying to upload is on
the file system, not available through the website. The error message itself
is from sandbox.freebase.com (using posting URL  $uploadURL= "
http://sandbox.freebase.com/api/service/upload"; ).

Does anyone have a php/libcurl image upload example working?

Kind regards,
Indy

Message-ID: <A2C68D68-8E94-410C-8C48-3921802D1C7D@eppsteins.net>

Hello again,

I received some excellent feedback yesterday and was able to  
incorporate it into the code today, along with some significant  
refactoring and improved documentation. If you're interested please  
check out the most recent code:
http://freebaseapi.rubyforge.org/svn/trunk/freebase/

or read the docs at:
http://freebaseapi.rubyforge.org/svn/trunk/freebase/rdoc/index.html

New Features:
No need to call Freebase::Type.define('/music/artist') before  
accessing Freebase::Types::Music::Artist (thanks to pat allan for this  
suggestion and code examples)
Ability to add custom methods to instances of Freebase types using a  
mixin and naming conventions.
Support for nested queries to retrieve multiple levels of associations  
in a single query

Open Questions/Concerns:
:fb_object => true should be added to the subquery whenever sub- 
querying an association so that a distinction can be drawn for the  
following differences in validation logic between object types and  
core types:
objects have multi-valued types, core types do not and you may not  
query a core type with [] you have to use null.
values of core types do not have an id and you may not specify 'id' :  
null in the query of a core type.
In both of these cases, the validation seems arbitrarily enforced;  
returning ['/type/text'] and 'id':null back respectively are in line  
with the other behaviors of the system, in my estimation.
I'm getting nulls from collections associations from Artist -> Album  
and from Album -> Track. I understand the null names problem now and  
am handling that appropriately per the recommendations in my new  
query. But I don't understand why a null would be returned as an  
element of an array. Please let me know whether to begin searching for  
a code defect on my end.

Thanks,
Chris

The code example again using the latest api:
# Usage:
#  ./script/runner vendor/plugins/freebase/examples/albums.rb "The  
Police"

# add these methods to the Track class
module Freebase::Mixins::Music
   module Track
     def formatted_length
       "#{self.length.to_i / 60}:#{sprintf("%02i", self.length.to_i %  
60)}"
     end
   end
end


artist = Freebase::Types::Music::Artist.find(:first,
   :conditions => {
     :name => {:value => ARGV[0], :lang => {:name => "English"}},
     :album => [{
       :fb_object => true,
       :name => {:value => nil, :lang => {:name => "English"}},
       :release_date => nil,
       :track => [{
         :fb_object => true,
         :length => nil,
         :name => {:value => nil, :lang => {:name => "English"}}
       }]
     }]
   }
)

artist.albums.each_with_index do |album, i|
   next unless album # XXX I don't know why I'm getting random nils  
here.
   puts "#{i+1}) #{album.name} (#{album.release_date || '?'})"
   album.tracks.compact.each_with_index do |track, j|
       puts "\tT#{j+1}. #{track.name || '???'}  
(#{track.formatted_length})"
   end
end

Dear developers,

Do you wish that there was a high-level overview about writing
Freebase-powered applications? Something to read first before diving
into detailed documentation?

I started writing a short "Getting started developing Freebase
applications". This is the page I was looking for when I started
developing my first Freebase app.
http://www.freebase.com/view/guid/9202a8c04000641f8000000006de254d

I'd be very grateful for your feedback on this page. Would it have
helped you write an app?

Hi Chris,
Thanks for the reply. Starting to make more sense, I can't see how I would
use games_on_this_platform then? I.E. what can I do with it? My query was
the same as on the Query Builder/Editor which did return results so it was
odd that PHP did not. Anyway, I've made good progress and now have results
coming back!

One quick question though. I am adding a limit to my query, above the
default 100. However when I do this it does not return results for my query.
If I take the limit out, I get results. Any ideas? Is there a way of getting
it to return ALL matches without limit?

Query is now as follows:

$q2 = array(array("/common/topic/image" => array(array("optional" => true,
"id" => null)),
 "type" => "/cvg/computer_videogame",
 "name" => null,
 "id" => null,
 "sort" => "name",
 "release_date" => array(),
 "cvg_genre" => array(),
 "versions" => array("platform" => array("id" => null, "name" => null,
"name~=" => "Xbox 360")),
 "limit" => 150
));

Cheers,
Chris

If you get no results without the limit, it's probably timing out on  
the server.

You'll need to use a cursor to request "pages" of data at a time.  On  
freebase.com,
search for "MQL Cursors" and you'll get a few useful hits, including  
some examples:

http://www.freebase.com/view/search?limit=30&start=0&query=mql+cursor

You should probably start with the documentation here:

http://www.freebase.com/view/guid/9202a8c04000641f800000000544e139

I wonder if the problem is just that the query isn't being placed  
within the request envelope. That would make it work in the editor but  
not via code. The request you send via mqlread should look like this
{ 'qname' : { 'query' : query_in_the_query_editor }}

This was a gotcha for me on a couple of occasions until I abstracted  
it away.

Hi Guys,
Tim - thanks for the info, I'll look into MQL Cursors.

Chris - I checked to see if the query produced was the same and I believe it
is. This is what PHP outputs:

{"qname":{"query":[{"\/common\/topic\/image":[{"optional":true,"id":null}],"type":"\/cvg\/computer_videogame","name":null,"id":null,"sort":"name","release_date":[],"cvg_genre":[],"versions":{"platform":{"id":null,"name":null,"name~=":"Xbox
360"}},"limit":150}]}}

I ran the above query in freebase and it produced results. This is the PHP
that passes my query through:

// Put the query into an envelope object
$envelope = array("qname" => array("query" => $queryobj));

// Serialize the envelope object to JSON text
$querytext = $this->json->encode($envelope);

Thanks,
Chris

Hi Steve,

The property /freebase/type_hints/hinted_type was removed as part of  
some clean up in freebase.  We are using hint properties directly on  
the type and properties.

Unfortunately, I failed to communicate this to the developer list and  
I apologize for that.

Properties that have been removed:
/freebase/type_hints/hinted_type
/freebase/type_hints/property_hints
/freebase/property_hints/hinted_property
/freebase/property_hints/property_hint_of

Types that have been removed:
/freebase/hinted_property
/freebase/hinted_type

I'll be more careful in the future and be sure to notify this list  
well before making any changes.

Bryan

Message-ID: <001301c84e44$2f1495c0$bc01a8c0@p4>

The links in my previous message have expired, so please disregard them.
I'd like to revisit this, now that most folks will be back from the
holidays, and hopefully publish it to Freebase.com soon.  There are two new
types: "written work" and "illustrated work". These will be used as
"supporting types" on all manner of written and/or illustrated topics (book,
book edition, poem, short story, review, short non-fiction, play), and will
replace some of the redundant properties on these types (author, editor,
poet, playwright, illustrator, cover artist). They also provide more
flexibility, and allow (for example) an illustrator to be added to a book
(in cases where every edition of the book has the same illustrations) or a
book edition (where different editions may have different illustrations), or
for an editor to be added to a book edition, rather than a book.
 
The schemata are here:
http://sandbox.freebase.com/view/schema/book/written_work
http://sandbox.freebase.com/view/schema/book/illustrated_work
 
Examples can be found in the topics lists for these types, but I want to
call out a few:
http://sandbox.freebase.com/view/guid/9202a8c04000641f8000000006e83b03
("Kipling's Science Fiction": a book with an author and an editor, and which
has different cover artists in different editions)
 
http://sandbox.freebase.com/view/guid/9202a8c04000641f8000000006e83b60 (The
Norton Critical Edition of "Middlemarch", which has an editor on the book
edition, but not on the book itself [this is not possible in the current
schema]).
 
http://sandbox.freebase.com/view/guid/9202a8c04000641f8000000006e83bea (An
interview -- the new types will make the existing "interview",
"interviewer", and "interviewee" types unnecessary)
 
Please take a look around, and let me know what you think.
 
Jeff

I've put in the illustration model: take a look here:
http://sandbox.freebase.com/view/schema/book/illustrated_work
I've put in two samples: one in which all editions of the book have the same
illustrator (http://sandbox.freebase.com/view/make_way_for_ducklings), and
one (well, two) in which there are different illustrators for different
editions of the book:

The cover artist thing is a good idea. I'm now imagining a "illustratorship"
type (I know, that's a lame name; I won't really call it that) that could be
used similarly to authorship, but which could be applied to magazine issues,
book editions, and books (and maybe some other things). Enum properties
would probably include "illustrator", "cover artist", "cover design", and
maybe some of the comics values -- pencillor, colorist, inker, letterer; but
this list will grow organically. An open question would be whether the
subject of an artist's monograph would properly be in the "writer" field or
"illustrator" field. But this is tractable.  I'll have to re-post the schema
when sandbox refreshes, so I'll see if I can add this to it as well.

While this will make it slightly harder to find information for the simple
case (author of a book) I think this will make it much easier to model the
more complex types of contributions to a published work.

You should consider replacing Magazine's Cover Artist with a Cover
Contributor. I'm sure there are a few other types where this could replace
multiple properties. (ie. Comic Books) 


On 12/13/07, Jeff Prucher <jeff at metaweb.com> wrote: 

There have been several requests made, over the last few months, to allow
for more flexibility of attributing authorship and other contributions to
written works, and also to add various properties to a number of types in 
the publishing domain. Toward this end, I've created a new type, "written
work" that will be an included type on all the various types that represent
written works -- book, short story, poem, short non-fiction, review, and 
translation.

The new type is currently on sandbox. I'd appreciate it if anyone who is
interested could take a look at it and let me know what you think. Please
look before Monday evening (Pacific Time), since sandbox will be refreshed 
then.
http://sandbox.freebase.com/view/schema/book/written_work

I've filled out the contents of the April 2007 issue of the Magazine of 
Fantasy and Science Fiction as an example. Click the various items in the
contents property to see the type in action.
http://sandbox.freebase.com/view/guid/9202a8c04000641f800000000514f951
<http://sandbox.freebase.com/view/guid/9202a8c04000641f800000000514f951> 

One feature is to treat authorship (or similar form of creative
contribution) as a compound value type which will allow for multiple types
of contribution to be recorded in the same property and for all the 
disparate types of works to be listed together on the contributors' pages.
Currently, author and editor are treated as separate properties; having a
single property will allow Freebase to reconcile more easily to other 
data-sources, which usually store these in the same field. This will also
allow us to record books where the illustrator is tied to the book itself,
rather to individual editions (as in most children's picture books, but as 
opposed to, say, an illustrated edition of Huckleberry Finn).
See http://sandbox.freebase.com/view/guid/9202a8c04000641f8000000006c3521e
<http://sandbox.freebase.com/view/guid/9202a8c04000641f8000000006c3521e> 
and http://sandbox.freebase.com/view/make_way_for_ducklings for some further
examples.

Another of the new type is that a number of other properties can usefully be

shared by all types of written works, rather than being distributed onto
each. These properties are: original language, date written, copyright date,
date of first publication, and online versions. Others will probably arise, 
but this seems like a good set to start with.

(I'm copying the developers list in case anyone is writing an application
using any of the publishing domain types.)

If there is an "End Date" then you don't work there anymore.  But  
Clint Hope (in Freebase) has an end date for working at AMI of 2030,  
which means he still works here - but the above query says he  
doesn't.  You can't remove the end date which is a different kind of  
FB bug, but I'm wondering how we can make a query that returns any  
instance where there is not a date before today, and which would  
include 'null'.

The query is a little difficult to debug since neither "forbidden" nor  
"required" are documented anywhere in the MQL documentation so I'm  
kind of flying blind here...

Thanks,
Kirsten

You can find all of my jobs that end before today with this query:

{
  "query" : {
    "employment_history" : [
      {
        "company" : null,
        "to" : {
          "type" : "/type/datetime",
          "value" : null,
          "value<=" : "2008-01-04"
        }
      }
    ],
    "id" : "/guid/9202a8c04000641f8000000003cbef5c",
    "type" : "/people/person"
  }
}

This requires that the gig have an end date, and that its value be less than or equal to today?s date.  (This does mean that a job whose end date were only ?2008? or ?2008-01? would compare as true, but we don?t have date-time?specific comparators yet.)

Hi,

I tried doing an empty HTTP POST to /api/service/mqlwrite, but I get an
HTTP 405 error, and the cache is not refreshed. What exactly is the
recommended method for resetting the cache?

Right now I am doing a "harmless" write, which seems to work, but it is
kinda ugly. i.e write this:

"query": {
   "id":"/topic/en/kqed"
}

Hi Arthur,

The logs seem to indicate that those 405s are being generated in 
response to HTTP GETs. The "refresh cache" functionality is currently 
defined only for an empty POST to /api/service/mqlwrite. Can you double 
check that your code is POSTing?

Ah, you are right. It turns out that Actionscript silently turns an
empty POST into a GET. Sorry about that.

It looks like I can't do an empty POST from AS3, so I'll stick with my
other hack.

Subject: [Developers] How do I find symmetric properties?
Message-ID: <20080105030822.GB20712@metaweb.com>


How can I discover with some combination of MQL queries and
programmatic post-processing the list of all symmetric properties are
in Freebase?  Examples of such properties include:

/location/location/adjoin_s
/people/person/spouce
/people/person/siblings

Perhaps there is some schema attribute that indicates symmetry?

Message-ID: <7110c7dc0801051447q1e9b8ff8kccc9b6edc83dff1c@mail.gmail.com>

Hi, we're trying to ask freebase how many topics of a particular type exist.
Below is what we tried, but it doesn't work - is this even available?

{
  "query" : [
    {
      "count" : null,
      "type" : "/user/corallink/default_domain/underwater_location"
    }
  ]
}

The workaround would be be to query and then count on the client side, but
that can potentially be wasteful from a bandwidth point of view.

Thanks,
Indy

The (undocumented) syntax is "return":"count"

So this is what you're looking for:
{
   "query" : [
     {
       "return" : "count",
       "type" : "/user/corallink/default_domain/underwater_location"
     }
   ]
}

Will that return the number returned or the total that exist when

Hello FreeBDevs:

So we finally got over the hump here; we fired up 'tcpflow' (awesome network
diagnostic tool, by the way, easier than tcpdump) to monitor the exchange
between the local system and freebase.

-The Broken-
Freebase's 'raw' upload url (sandbox.freebase.com/api/service/upload) only
accepts 'POST' requests but doesn't know how to deal with
multipart/form-data as a content type.  PHP/libcurl defaults its POST to
Content-Type: multipart/form-data,  and embeds the image inside of that
multipart envelope.  Below is the tcpflow output with the broken code, minus
some extraneous stuff (192.168.0.150 is the local system, 208.068.108.121 is
sandbox.freebase.com):

192.168.000.150.46220-208.068.108.121.00080: POST /api/service/upload
HTTP/1.1
Content-Type: image/gif
Content-Length: 13365
Content-Length: 13555
Expect: 100-continue

192.168.000.150.46220-208.068.108.121.00080: Content-Type:

208.068.108.121.00080-192.168.000.150.46220: HTTP/1.0 400 Bad Request


***This lead to the cryptic "cannot identify image file" response from the
freebase server.***


-The Fix-
Straightforward, but there are no examples of this I could find in Google to
use CURLOPT_READDATA instead of CURLOPT_POSTFIELDS:

Replace one line:
   curl_setopt($request, CURLOPT_POSTFIELDS,$content);

With these two lines, dropping the @ from the front of the file name:
    $fp = fopen ($content, "r");
    curl_setopt($request, CURLOPT_READDATA, $fp);


-The New-
The working interaction is as follows, note there is no mention of
multiparts:

192.168.000.150.59161-208.068.108.121.00080: POST /api/service/upload
HTTP/1.1
Content-Type: image/gif
Content-Length: 13365
Expect: 100-continue

208.068.108.121.00080-192.168.000.150.59161: HTTP/1.0 200 OK


Hope this leads to less pulled out hair for someone.

Regards,
Indy

For companies, is there any interest in linking companies to their

Wikipedia?  I don't mind adding it, but there is no appropriate slot

Key products seems to be important information for a company.

It would probably make sense to have some sort of "products producer" 
co-type. The producers would have a "products produced" link to the 
"producer" field of the corresponding "product" type.

Not every company produces products, and there are some products that 
are produced by groups other than companies.

Other than that, it sounds like great information to track.

The "Products producer" type with a "Products produced" property sounds
pretty good to me. The "Product" type a little less so. Would every tangible
topic (including people) need to be typed as a product? What defines a
product that separates it from other tangible topics? I agree that this kind
of type could be very useful and there should be reciprocation between
product and producer but I'm not excited about this approach to doing it.

-Ed

P.S. This conversation is probably more relevant to the Data Modeling list
so I'm cc'ing it.

The products type, I assume, would have other information that you would 
need for your standard sold product.

UPC, weight/volume, possibly some cost data, etc.

A person wouldn't be considered a product because in most parts of the 
world, humans aren't sold in stores.

If not a product type, what type would you slip the product producer 
property into?

Shawn,
That's a great idea.  And I agree with Dan that products produced is  
an optional property, but capturing those key products would be  
terrific, especially if they are already available from the UPC  
Creative Commons data.

I looked at the UPC database site some more, and (unfortunately) it  
doesn't seem to have a lot of the manufacturer data filled in.  I  
went to GS1 US site, but it didn't look like that data was available  
there either? Does anyone know where this information might be  
available under the Creative Commons license?  Thanks!

I think it looks like this: a property's expected type has to be a CVT 
(/freebase/type_hints/mediator) and the reverse of that property has to 
be non-unique.

Hi Indy.

The raw_upload service behaves exactly as you described. If you want to 
use a form based POST to upload files, you can use the form_upload 
service which will process a CURLOPT_POSTFIELDS request properly. The 
raw upload service expects the data to be in the body of the POST.

We are currently working on getting a more comprehensive set of 
documents on freebase describing the services available to developers. 
It should be up in the Freebase help section shortly.

Thanks.

I think Alec's right, except that the master property has to be unique, not
the reverse. That is to say, the property's expected type must be a CVT, and
the CVT most hold the master property, which must be non-unique.  (If the
non-CVT type has the master property, the relationship will not be
symmetric.)

That said, the truth is more complicated. For example the property,
/award/award_honor/award_winner meets these qualifications. Arguably, it is
symmetric in that it indicates that, for example, Al Gore and the
Intergovernmental Panel on Climate Change are co-award winners (of the 2007
Nobel Peace Prize), but this is not necessarily what you might usually think
of as a symmetric property.

if you include a limit, it will return anything up to that number, for  
example:

   "query" : {
     "limit" : 50000,
     "return" : "count",
     "type" : "/film/film"
   }

If there is no limit, limit:0 is assumed.

For public types, sometimes the instance count is too large to  
enumerate quickly and there is a type hint for these which is updated  
daily.

   "query" : {
     "/freebase/type_profile/instance_count" : null,
     "id" : "/people/person"
   }

Subject: [Developers] Wikipedia key string encoding
Message-ID: <C3AC321A.CC8%max@powerset.com>

Hello,

Is there any documentation regarding the type of string encoding used for
wikipedia keys in freebase records? Specifically, I'm wondering about the
encoding used to represent non-alphanumeric characters in the 'key'
attribute, where namespace is /wikpedia/en. I suspect it's something simple,
but I couldn't find the relevant info in the developer docs, so I figured
I'd ask before diving into trial and error attempts.

Thanks,

Max @ powerset

yes, the key encoding is documented in section 2.2.6. of the MQL manual.

Hi,

 

We are getting an "unsubscriptable object" error when submitting a query

what this means?

 

Here is the query:
