The documentation describes a meta collection as a combination of 2 (or more) different APIs...
By default, a meta API endpoint returns all data from all of its
sub-APIs, organized by collection.
But, what I find is that it does not do this. It grabs partial data from some sub-APIs and fails silently, without logging an error.

The data structure is verbatim the same. Why don't they combine under meta API?
Testing
A meta API combination worked with 2 APIs, each with one collection.
When there is more than one collection defined, certain combinations of APIS combined partially. Each collection filled with the contents of one or the other API, but never both.
The 3 APIs I need to combine result in one site's results in all of the collections, and nothing from the other two in any collection, and no error logged.
The flaky results seem tied to the collections. But I've moved on to a klugey temp fix, which is to call each API separately and combine the JSON results in my app. 3 API calls instead of one. Might be looking for another tool, soon.
Now it works
Since I posted this question in October, KimonoLabs has updated their app and I am now having consistent success with creating and using a Meta API for the set of single APIs I posted above.
That's the positive.
The catch is that you cannot use the URL parameters in a meta API, so if you'd written post-process modify results functions, they will not be executed, even if you use kimmodify=1.

I'm trying to retrieve all the synsets categories of a given word in Babelnet via RESTful API.
E.G.
If you go to http://babelnet.org and search for Java you can see 17 results beloging to 7 categories (Game and videogames, Drink and beverage, Information Technology and so on).
How can I get the category of each synSet via API?
In the API list there is no reference to the categories..
Thank you all.
You can get all synset's categories using the getCategories() method.
BabelSynset by = bn.getSynset(new BabelSynsetID("bn:03083790n"));
List<BabelCategory> cats = by.getCategories();
Let's say I have the following entities in my libraries app - Library Room, shelf, Book.
Where Room has N shelves, and shelves have N Books.
Now the following url brings me a list of books whose
library is 3, room no. is 5 and shelf no. is 43.
.../library/3/room/5/shelf/43/books
Assuming shelf 43 is unique per room only
(There is shelf 43 also in other rooms)
and Rooms are not unique (There's a few room no. 5 ) in the library.
Here is my questions:
I want to filter with more fields on the entities, here is what i want to do
(representation not in rest):
.../library/id=3&type=3/room/decade=21&topic=horror/shelf/location=east&/books
This is not rest.
How do I represent it in rest?
Notes:
I don't want to do this way
.../books¶m1=X¶m2=X¶m3=X¶m4=X
because not all params are related to books.
Couple of things that you need to look into while designing your apis.
1) are type, decade, topic etc required fields? if so, I will probably make them a part of the path itself, such as:
../libraries/{libraryId}/type/{typeId}/rooms/{roomId}/decades/{decadeId}/topics/{topicName}/shelves/{shelfId}/locations/{shelfLocation}/books
Here I am assuming that each library can have rooms which have unique room ids per library, each room can have shelves which has unique ids/locations per room (and so on and so forth). Yes, the url is pretty long, but that's kind of expected
2) if these fields are not required, you could use a different approach which is a bit less verbose but a bit more confusing for client developers who have never used such approach here. Here's a straight up example Restful Java with JAX-RS by Bill Burke
#Path("{first}-{last}")
#GET
#Produces("application/xml")
public StreamingOutput getCustomer(#PathParam("first") String firstName,
#PathParam("last") String lastName) {
...
}
Here, we have the URI path parameters {first} and {last}. If our HTTP request is
GET /customers/bill-burke, bill will be injected into the firstName parameter and
burke will be injected into the lastName parameter.
If we follow this somewhat academic approach (I have not seen this implemented on many platforms. Most platforms normally go with approach # 1, a more verbose but clear approach), your URL would look somewhat like this:
../libraries/{libraryId}-{typeId}/rooms/{roomId}-{decadeId}-{topicName}/shelves/{shelfId}-{shelfLocation}/books
This way, if the client developer doesn't pass in the non-required fields, you can handle it at the business logic level and assign these variables a default value, for example:
../libraries/3-/rooms/2-1-horror/shelves/1-/books
With this url, libraryId = 3, typeId = null (thus can be defaulted to it's default value) and so on and so forth. Remember that if libraryId is required field, then you might want to actually make it a part of the pathparam itself
Hope this helps!
The support forums on ESPN.com recommend using Stack Overflow with the ESPN tag. That's why I'm here.
I'm trying to obtain a list of all NCAA college basketball teams using ESPN's Teams API. I started with this GET request:
http://api.espn.com/v1/sports/basketball/mens-college-basketball/teams?apikey=MY_API_KEY
That gave me a list of teams, but many of them are missing. For example, there is no Nebraska. So then I thought that maybe I need to get a list of teams by conference. So I read this in the documentation:
GROUPS: Allows for filtering by "group" or division, e.g. AL East, NFC South, etc. For group IDs and their corresponding values, make a request to http://developer.espn.com/v1/{resource}/leagues. Not applicable to golf and tennis.
So then I try to make a request to `http://developer.espn.com/v1/sports/basketball/mens-college-basketball/leagues?apikey=MY_API_KEY' and it says the page does not exist.
Is this a bug or user error?
First, I think you forgot sports in the resource. Try this:
http://api.espn.com/v1/sports/basketball/mens-college-basketball?apikey=MY_API_KEY&leagues
That will return a mapping of integers to conferences it seems according to the documentation.
That fetched me:
{"name" :"Atlantic Coast Conference","abbreviation" :"acc","groupId" :2,"shortName" :"ACC"}
...and much more.
Then once you have that, let's say 2 = ACC. You should be able to do this:
http://api.espn.com/v1/sports/basketball/mens-college-basketball?groups=2&apikey=MY_API_KEY'
to get everything on ACC mens' basketball teams.
Bear in mind the API is in beta though.
I could not figure out how to get a list of conferences, but I found out how to get the missing teams. When I was making the first get request, it was limiting me to 50 results by default:
http://api.espn.com/v1/sports/basketball/mens-college-basketball/teams?apikey=MY_API_KEY
They have a sandbox where you can play with your parameters, and I saw a limit and offset option:
http://developer.espn.com/io-docs
To get more than 50 results, you have to make multiple requests using the limit and offset parameters.
First Call:
http://api.espn.com/v1/sports/basketball/mens-college-basketball/teams/?limit=50&offset=0&_accept=text%2Fxml&apikey=MY_API_KEY
Next Call:
http://api.espn.com/v1/sports/basketball/mens-college-basketball/teams/?limit=50&offset=50&_accept=text%2Fxml&apikey=MY_API_KEY
And so on...
I have a problem with MVC displaying list of many to one objects using an http post. How do I perform a db.SaveChanges() so that it includes each claw from my form submit?
example primary entity:
Cats table has
Cats: id, and cat name only.
many to one cat entity (notice CatId):
Paws: Paw Number, claw1, claw2, claw3, claw4, claw5, and finally CatId
each claw number represents a sharpness index.
On my main form I have only a single cat and have all 4 paws and its sharpness index listed out.
Now if I want to save each of the 4 paws and claws for this one cat how do I get save db.SaveChanges() if there is no it pointing to Paws in the Cats table. This seems so basic but haven't been able to tweak it yet. I've even set the #Html.ForEditor control to have an id of Paws and even Paws.Claws or Paws.Claw doesn't seem to work.
I'm trying to use MVC 4.5 for this.
Preamble
I'm developing a card game server in Rails. The application records what a player is expected to do via a tree of instances of the PendingAction model.
class Player < ActiveRecord::Base
has_many :cards
has_many :pending_actions
end
At any time, the player needs to act on any leaf PendingActions - there may be more than one, for instance:
1. End turn
|
+- 2. Do thing A
| |
| + 3. Do thing pre-A
|
+- 4. Do thing B
|
+ 5. Do thing pre-B
The view code presents the player with one or more forms, requesting their choice for each leaf action. For instance, in the above case, forms would be presented to solicit input for actions 3 and 5.
When the player makes a choice for, say, action 5, that action is destroyed. However, processing their choice may cause them to need to make another choice before the parent (action 4) can happen. Like so:
1. End turn
|
+- 2. Do thing A
| |
| + 3. Do thing pre-A
|
+- 4. Do thing B
|
+ 6. Do other thing pre-B
Action 4 therefore needs to be on-hand, so action 6 can be created as its child. At present, I am simply passing action 4 around as a function argument. However, I've just come across a situation where it would really help to be able to have access to it in a before_save hook on a Card object.
Question
Where is the best place to store an object, associated with a Player, that I can access from all models related to that Player, which is valid throughout - but not beyond - a single HTTP request?
I am running under Heroku, with 1 dyno - so I believe I'm single-threaded.
It depends on which environment you work, but lets assume that this is single-threaded environment. Next, first thought was to create instance attribute to manually assign and retrieve anything. It is will work fine when Player instance is the same for all places.
If not, I suggest to introduce class variable, some sort of cache, that will hold Player#id => <some_obj> reference, and with helper accessors, like Player#some_obj which will query Player for object by self.id.
That way you will be ensured that for all Player with the same Id, some_obj will be the same. Also, you will need to deside, when to empty that class-cache. For Rails, i suppose after_filter is good enough.
