Thanks for the pointer gmackenz. I was searching for the wrong terms and getting zero results. You pointed me in the right direction:

Your excellent question here (and also on the Query Builder page) might already be answered in the archives of the App developers mail list (linked to on the App page). In fact I know the question about getting the description was answered recently on one of our two mail lists.

2008-06-10T23:01:56.0012Z

I need to obtain data across multiple guid's within a single query. E.g. this simple query gets the name for a single guid. Is there a way to pass in multiple IDs to get back information on each? I.e. I don't want to perform 100's of individual queries.

{

"id" : "/guid/9202a8c04000641f800000000023907a",

"name" : null,

}

Thanks,

The Complete Metaweb Application Development Reference Guide (API and MQL): Finding user defined types

2008-05-28T14:49:40.0005Z

Helo all,

I am trying to analyze user define types in freebase - types defined the users in their default domains or user defined domains, not yet promoted to the standard freebase domains. I have been trying to make up an MQL for that but it doesn't seem to be easy (as I cannot do pattern matching on the "id"). Any ideas?

The Complete Metaweb Application Development Reference Guide (API and MQL): Making a category list

2008-04-16T19:33:28.0007Z

Sports is a "domain category", which has a list of domains (via a property). Sports/Basketball (id: /Basketball) is a domain, and when you say a "list of categories" in that domain, you're referring to the types in that domain. So, the query to look up types in a specific domain by id /Basketball is:

{
  "query" : [
    {
      "id" : "/basketball",
      "type" : "/type/domain",
      "types" : [
        {
          "id" : null,
          "name" : null,
          "type" : "/type/type"
        }
      ]
    }
  ]
}

The Complete Metaweb Application Development Reference Guide (API and MQL): Making a category list

2008-04-16T15:18:48.0005Z

I'm writing a small app on FreeBase.
I'm trying to build a category tree which shows the main categories (sports, arts & crafts, etc.) and lets the user drill down to additional sub categories.
Is there something like this already built which I can use?

I notice that I can get a list of the categories for "Sports" like this:

{ "query" : [ { "domains" : [ { "id" : null, "name" : null, "type" : "/type/domain" } ], "name" : "Sports", "type" : "/freebase/domain_category" } ]}

but I can't figure out how to get a list of categories under "Sports/Basketball"

The Complete Metaweb Application Development Reference Guide (API and MQL): Perl?

2008-01-11T20:41:51.0007Z

No, and I don’t think any other community-created modules are mentioned here either. Someone has added a Python client to the list of Freebase Application instances; you could add WWW::Metaweb there, too.

No mention of the WWW::Metaweb Perl Module?

The Complete Metaweb Application Development Reference Guide (API and MQL): language argument

2007-11-26T21:50:30.0000Z

Though the infrastructure is there for supporting multiple languages when you specifically ask for values, we haven't yet implemented the full support for being able to specify the language in the query envelope.

When that is implemented, you'll be able to say something along the lines of:
{"lang": "/lang/es",
"query": {"id": "/foo/bar", "name": null}}

to get the spanish name of /foo/bar

We'll be sure to make a large announcment when there is significant progress on this front.

The Complete Metaweb Application Development Reference Guide (API and MQL): language argument

2007-11-21T07:06:43.0016Z

In Chapter 5, it is mentioned that there is an argument for the mqlwrite (possibly mqlread too?) service which specifies the default language for the text values, but it is not documented anywhere. Is there such an argument and if yes, what is its usage?

2007-10-16T16:41:58.0005Z

examples A.4 and A.5 are not actually in the appendix.
example "4.8. metaweb.js: Metaweb queries with script tags" does not exist.

Good point. I'll look into it.

Just as an FYI, we are also working on a different approach to producing API reference documentation that should help us keep it in better sync with what's actually in production. I know that's been an issue.

Can you make the API searchable here?

We should probably remove the link for now. We changed the way we're maintaining this content and don't have an up-to-date XML representation of the contents anymore. We're going to try to create a single unified view of all the chapters, but this may be a few weeks out.

Can somebody please update the PDF file? I downloaded it to read and discovered it was obsolete.
