Angular module for BBC Linked Data.
First of include the file bbcld.module.js in your project, this will register the module allowing the services to cling on to it. The module has been developed so that you only have to include the modules you want to use.
The usage is simple.
module.method(_options_)The module returns a promise when called, this the native way Angular keeps track of Asynchronous requests. To bind something to the result, use the .then(succesFunction, failFunction) method, specifying the function it should perform if it succeeds in the first argument and it's failure in the second. The success and failure functions take one argument, data, which is an object containing all the information related to the HTTP request inherited from ngHttp ($http).
module.method(_options_).then(_successFunction_, _failureFunction_);$scope.responses = [];
var success = function(data) {
$log.info(data);
$scope.responses.push(data);
};
var fail = function(data) {
$log.error(data);
$scope.responses.push(data);
};

});juicer.getArticles({_params_})query:
keywords to search for. Searches in title, description and body of the article.
sources:
scopes the results to certain sources. Multiple products can be specified by adding multiple sources[] values. The parameter is a number that correspond to a source id.
facets:
filter the results by facets. The facets parameter is a URL-Encoded resource from dbpedia. Multiple facets can be specified by adding multiple facets[] keys and values. The parameter is a string and it refers to a dbpedia resource.
size:
number of results to be returned. The parameter is a number.
offset:
number of results to skip. It can be used with size for pagination. The parameter is a number.
publishedAfter:
fetch articles published after a date. The date format is in UTC. Ex: 2015-02-02T00:00:00.000Z.
publishedBefore:
fetch articles published before a date. The date format is in UTC. Ex: 2015-02-02T00:00:00.000Z.
recentFirst:
Sort results by date (with most recent first) instead of by relevance to keywords. The parameter can be either yes or empty.
likeText:
Return a list of articles with a text similar to the parameter. The like-text parameter is a string.
likeIds:
Return a list of articles similar to other articles. The parameter is a string (internal id).
juicer.getArticle(_juicer UUID or URL_)query:
Keyword to search for. It searches in the article. Can be a Juicer UUID or a URL
juicer.getArticleById(_juicer UUID_)Get the article directly from the endpoint by passing the ID
juicer.getArticleByUrl(_URL_)The Juicer ID of every article is derived from a SHA1 hash, So if we pass the URL to a SHA generator, we will probs get a valid Juicer ID.
juicer.getSources({_params_})query:
Keyword to search for. It searches in name of the source.
Returns: JSON-LD

BBC Things does not support CORS, so it wont work in any browser!!!
Returns: JSON-LD
Include: things.service.js
things.getById(_BBC Things ID_)things.getById(_BBC Things URI_)Have not yet been developed, so are just shim's for now
The Juicer module depends on angular-sha1 for doing a reverse lookup for URL's in the Juicer.
Run grunt for building and grunt serve for preview, the app that will load up is the app from app/ and will do all the calls to available endpoints returning the results on the screen.
The test is now missing an environment
You can add an environment with for example an env.js file
