A quick introduction: I straddle the middleware and infrastructure teams at Metaweb. Primarily I design and implement the MQL query language, although I have my fingers in a bunch of other areas from time to time. If you're new to freebase and MQL or would like to refresh your memory on the details you can find the MQL documentation at: http://www.freebase.com/metaweb/documentation/ If you have other questions about MQL or are interested in why it does (or does not) have a certain feature, send your comments to this mailing list. MQL is quite different from most existing query languages and I'm very interested in feedback about the design. I look forward to seeing your comments, Tim From fire at kidbombay.com Fri Mar 9 05:21:44 2007 From: fire at kidbombay.com (Ketan Anjaria) Date: Thu, 8 Mar 2007 21:21:44 -0800 Subject: [Developers] Movie Properties Message-ID: How do you get the blurb for a movie? { "query":[{ "name":"Titanic", "*":null, "type":"/film/film" }] } Doesn't return a property with that information.

We currently view blobs (not just text, but also images) as data that needs to be separately requested via /api/trans/ (which also controls what format you get it in.) We have discussed adding the feature to allow you to get some text or a blurb back as a property of the content object directly. This isn't currently implemented. If you look at the way our search service behaves; it also independently fetches the blurb for each article (so it would be among the first candidates to move to a new API if we had one.) Thanks for asking the question; it's good to know what features would be useful externally as well as inside Metaweb.

Mjt allows you to write HTML templates and fill them in with data from JSON web services, entirely in the browser. No server support is required - the app is delivered as static HTML and Javascript. It's easy to get started with, but also quite flexible. It's a novel approach to building AJAX-like apps.

Is it possible? Anybody have an answer for this one? I'm having a similar issue. I'd like to be able to look at all of the properties of an object without worrying about the type. The approaches I tried were ignoring the type: "query":[{ "*":null, "id":"#9202a8c04000641f80000000010c33ab" }] trying to say any types at all: "query":[{ "*":null, "id":"#9202a8c04000641f80000000010c33ab", "type":[] }] and specifying the types that the object has to get all the properties from both types: "query":[{ "*":null, "id":"#9202a8c04000641f80000000010c33ab", "type":["/common/topic","/freebase/software_ticket"] }] For various reasons none of these work. I understand why the second one fails; the magic meaning of the "type" field in the query field conflicts a little with the QBE style of MQL. At least at this stage of my understanding though, I'd expect the first and third to work.

The restriction is indeed artificial and I agree it would be good to remove it. If you're not interested in the value, there's no reason for MQL to require you to ask about it. It would be more difficult to return the value automatically. Consider the Bradbury Building (a location in Blade Runner): { "id": "#9202a8c04000641f800000000047b022", "type": [], "/common/topic/alias": [], "name": null } { "alias" : [ "Bradbury Apartment Building", "Bradbury Apartments" ], "id" : "#9202a8c04000641f800000000047b022", "name" : "Bradbury Building", "type" : [ "\/common\/topic", "\/film\/film_location" ] } This topic has a name and two aliases that all match ~= "Bradbury". Asking for: [{ "name": null, "name~=": "Bradbury", "id": null, "type": "/film/film_location" } produces [ { "id" : "#9202a8c04000641f800000000047b022", "name" : "Bradbury Building", "type" : "\/film\/film_location" } ] but asking for: [{ "/common/topic/alias~=": "Bradbury", "id": null, "type": "/film/film_location", "/common/topic/alias": null }] results in: { "info" : { "count" : 2, "result" : [ "Bradbury Apartment Building", "Bradbury Apartments" ] }, "message" : "Unique query may have at most one result. Got 2", "path" : "\/common\/topic\/alias", "query" : [ { "\/common\/topic\/alias" : null, "\/common\/topic\/alias~=" : "Bradbury", "error_inside" : "\/common\/topic\/alias", "id" : null, "type" : "\/film\/film_location" } ], "status" : "\/mql\/status\/result_error", "type" : "\/mql\/error" } as there is more than one matching alias. This is a case where inferring "/common/topic/alias": null from "/common/topic/alias~=": "Bradbury" would break the query, whereas if MQL does not return the value there is no problem to solve.

Thanks, that's good to know. Personally I'd also prefer the leave-it-out approach, but if there are strong partisans for the must-return-something approach, then you could do something that parallels the behavior of "*":null where "null" really means "null" or "[]" depending on context. Particular solution aside, do you want people to put MQL language suggestions like this in with the tickets? http://www.freebase.com/view/filter?id=/freebase/software_ticket Or is mentioning things here sufficient?

The binary data you get in the cursor is actually an encoding of the "position" of the next item in the given query. Minus a few bugs here and there, this means you can re-run the same query with the same cursor over and over and keep getting the same results back - I believe this will work even if the results change, because the cursor should be recording the state of the graph when the query was run. Think of it as kind of a 'bookmark' into the query results. (At least for the next few months however, you shouldn't persist cursors for longer than a few minutes - we have at least one pending change to the cursor format that will render current cursors useless..)

When you say "attributes of properties" what kind of attributes are you talking about? Properties themselves have a number of properties on them, including "expected_type" which is the type that the given value should have (i.e. so that /film/film/directed_by has an expected_type of /film/director) One thing that may be confusing here is that expected_type is not strongly enforced - it's really more of a hint to allow the query language to make assumptions about property values, which allows the syntax to be short when the expected_type of a property value does in fact match. I can explain this further if you want... the "key" thing may also be confusing because "key" is essentially a backpointer to the enclosing namespace. i.e. the "key" of /wikipedia/en/Anarchism is /wikipedia/en. Since a "namespace" is really just node that has a "keys" property, not all items in an id path are namespaces. For example, /wikipedia/en/Anarchism is not a namespace, but /wikipedia/en is.

In-Reply-To: References: Message-ID: <4602BB58.6040709@metaweb.com> Hi John, Welcome to Freebase! I agree that "key" and /type/key have special behaviour in MQL. They are important and common enough to be optimized internally. Hopefully the power they bring (the hierarchical path in an id like "/common/topic/article" or "/wikipedia/en/Anarchism") makes up for the slight inconsistencies in syntax. My belief is that most languages are stuck with inconsistencies in various places and the best you can do is try to minimize the impact on the language user. Some very popular languages (Perl and SQL are two good examples) have horribly inconsistent syntax, but are in common use and considered "easy to use" while others (Lisp is the classic case) have a very small and consistent syntax but aren't used that commonly and are considered "hard to learn". I'm also curious as to what you mean by "out of band attributes of properties". The closest thing I think MQL has to that is the "link" pseudo-property which enables you to examine the internal information of a particular property instance (such as who created it and when they did so.) This too is somewhat syntatically inconsistent (for example, "link" is not a property of any type.)

In-Reply-To: <4602BB58.6040709@metaweb.com> References: <4602BB58.6040709@metaweb.com> Message-ID: Hi Tim, many thanks for your warm welcome. I'm using "band" like we often use "space".. I got into "band" when focusing on web services design issues for tools (services), comparing the HTTP content-body (POST|PUT XML|JSON) with HTTP query-parameters (GET|POST url-encoded). As in "syntactic bands" where the HTTP query string has a very narrow band (little capacity for structure), and the content-body has a broad band capacity for structure. Makes for a quick analysis of tool (service) design issues. The debate here would be over a Property named "key", versus any Property having either Type Key or Attribute Key. So this is my getting to know Freebase, bringing along concepts from file formats and relational databases. For one, the Freebase key has a different conception from a relational database key. It's a unique Property value, but plays a different role in a graph than a key in a table.

Is there a reason you need a non-list if there's only one value? In other words, would: "varieties":["Cirrus uncinus"] be acceptable? If so, then just specify: "varieties":[] in your query, and you'll get the above result. Otherwise, there isn't a way to specify a conditional return type depending on the number of results. Generally, unless you're sure there's only one value, using [] as the value placeholder is a better idea, since otherwise you'll get an error on multiple values. You can always ask for result["varieties"][0] if you only care about one result. Or specify "varieties":[{"name":null,"limit":1}] if you only want one result but there may be many in Freebase.

I initially thought I would get the list of properties with datetime then iterate doing queries for each type that has a datetime property. I figured out how to get all properties that use datetime,
mjt.mqlread([{ "properties":[{ "expected_type":"/type/datetime", "name":null, "schema":{ "/freebase/type_profile/instance_count":null, "name":null } }], "sort":"-properties.schema./freebase/type_profile/instance_count", "limit": 75, "type":"/type/type" }])

In-Reply-To: References: Message-ID: There are several issues to address in doing this. First, Google Web Toolkit (GWT) supports building AJAX application in Java. It provides a nice wrapper around XMLHttpRequest. However, cross-site issues prevent that approach to work for normal Freebase application where the GWT application host and the Freebase query server run at different sites. Section 4.5.2 of Developing Metaweb-Enabled Web Applications (http:// www.freebase.com/view/documentation/) describes several workarounds to the cross-site issues. GWT's developer site provides information and an example of how to dynamically fetch JSON feeds from other web domains (http://code.google.com/support/bin/answer.py? answer=55954&topic=10394). Note: the approach works but the some of the description and the code snippets are buggy. In summary, an approach is to: a) use a dynamically created script tag with a mqlread URL and a callback parameter in the GWT application, b) use the GWT approach to define a JSON callback into Java from external Javascript. Second, aside from the errors in the above-mentioned GWT example, there are issues to be aware of. For example, because a GWT is loaded in a zero-size IFrame inside the main document, this prevents "x instanceof Array" from working with the data returned by JSON. For details, see the discussion in GWT Google Groups (http:// groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/ b750195091da28cb/1ba006b4577365a8? lnk=gst&q=instanceof&rnum=10#1ba006b4577365a8). Therefore, processing the JavaScriptObject provided by the JSON callback requires writing some JSNI code and using a workaround to test for arrays. Without further ado, here's an application example that displays the MQL query result in a GWT tree widget. http://www.webcollab.com/freebase/gwtmqlread/ Alison P.S.: GWT is available from http://code.google.com/webtoolkit/ > -----Original Message----- > From: developers-bounces at freebase.com > [mailto:developers-bounces at freebase.com] On Behalf Of William Pietri > Sent: Tuesday, March 20, 2007 3:16 PM > To: developers at freebase.com > Subject: [Developers] Calling Freebase from GWT? > > Has anybody managed to call the Freebase API from a GWT component? > I'm a > Javascript tyro, and I'm struggling to get it properly bound in > with JSNI. > My current hurdle, which I think I'll get past shortly, is getting > the call > to happen at all.

You can see it here: http://dev.scissor.com/querybuilder/ Current features: * no freebase login required * browses domain/type tree * builds simple queries for single type * works against sandbox Right now, I think it works well enough to help newbies get going with MQL, so I'm releasing it to the public. In upcoming releases. There are a couple of known issues: * it's very ugly, at least until I get some CSS help * it doesn't allow filtering on all types * clicking on a property name in the property browser puts it at the bottom of the list Likely upcoming features include: * filtering support for o dates o booleans o numerics * executing queries * proper handling of mediator types (like roles in a film) * nested browsing of type properties * sorts * limits * optional constraints Please try it out and let me know what you think!

A quick introduction: I straddle the middleware and infrastructure teams at Metaweb. Primarily I design and implement the MQL query language, although I have my fingers in a bunch of other areas from time to time. If you're new to freebase and MQL or would like to refresh your memory on the details you can find the MQL documentation at: http://www.freebase.com/metaweb/documentation/ If you have other questions about MQL or are interested in why it does (or does not) have a certain feature, send your comments to this mailing list. MQL is quite different from most existing query languages and I'm very interested in feedback about the design. I look forward to seeing your comments, Tim From fire at kidbombay.com Fri Mar 9 05:21:44 2007 From: fire at kidbombay.com (Ketan Anjaria) Date: Thu, 8 Mar 2007 21:21:44 -0800 Subject: [Developers] Movie Properties Message-ID: How do you get the blurb for a movie? { "query":[{ "name":"Titanic", "*":null, "type":"/film/film" }] } Doesn't return a property with that information.

We currently view blobs (not just text, but also images) as data that needs to be separately requested via /api/trans/ (which also controls what format you get it in.) We have discussed adding the feature to allow you to get some text or a blurb back as a property of the content object directly. This isn't currently implemented. If you look at the way our search service behaves; it also independently fetches the blurb for each article (so it would be among the first candidates to move to a new API if we had one.) Thanks for asking the question; it's good to know what features would be useful externally as well as inside Metaweb.

Mjt allows you to write HTML templates and fill them in with data from JSON web services, entirely in the browser. No server support is required - the app is delivered as static HTML and Javascript. It's easy to get started with, but also quite flexible. It's a novel approach to building AJAX-like apps.

Is it possible? Anybody have an answer for this one? I'm having a similar issue. I'd like to be able to look at all of the properties of an object without worrying about the type. The approaches I tried were ignoring the type: "query":[{ "*":null, "id":"#9202a8c04000641f80000000010c33ab" }] trying to say any types at all: "query":[{ "*":null, "id":"#9202a8c04000641f80000000010c33ab", "type":[] }] and specifying the types that the object has to get all the properties from both types: "query":[{ "*":null, "id":"#9202a8c04000641f80000000010c33ab", "type":["/common/topic","/freebase/software_ticket"] }] For various reasons none of these work. I understand why the second one fails; the magic meaning of the "type" field in the query field conflicts a little with the QBE style of MQL. At least at this stage of my understanding though, I'd expect the first and third to work.

The restriction is indeed artificial and I agree it would be good to remove it. If you're not interested in the value, there's no reason for MQL to require you to ask about it. It would be more difficult to return the value automatically.

Asking for: [{ "name": null, "name~=": "Bradbury", "id": null, "type": "/film/film_location" } produces [ { "id" : "#9202a8c04000641f800000000047b022", "name" : "Bradbury Building", "type" : "\/film\/film_location" } ] but asking for: [{ "/common/topic/alias~=": "Bradbury", "id": null, "type": "/film/film_location", "/common/topic/alias": null }] results in: { "info" : { "count" : 2, "result" : [ "Bradbury Apartment Building", "Bradbury Apartments" ] }, "message" : "Unique query may have at most one result. Got 2", "path" : "\/common\/topic\/alias", "query" : [ { "\/common\/topic\/alias" : null, "\/common\/topic\/alias~=" : "Bradbury", "error_inside" : "\/common\/topic\/alias", "id" : null, "type" : "\/film\/film_location" } ], "status" : "\/mql\/status\/result_error", "type" : "\/mql\/error" } as there is more than one matching alias. This is a case where inferring "/common/topic/alias": null from "/common/topic/alias~=": "Bradbury" would break the query, whereas if MQL does not return the value there is no problem to solve.
