NAME

WWW::GoodData - Client library for GoodData REST-ful API

SYNOPSIS

  use WWW::GoodData;
  my $gdc = new WWW::GoodData;
  print $gdc->get_uri ('md', { title => 'My Project' });

DESCRIPTION

WWW::GoodData is the client for GoodData JSON-based API built atop WWW::GoodData::Agent client agent, with focus on usefullness and correctness of implementation.

It provides code for navigating the REST-ful API structure as well as wrapper funcitons for common actions.

METHODS

new [PARAMS]

Create a new client instance.

You can optionally pass a hash reference with properties that would be blessed, otherwise a new one is created. Possible properties include:

agent

A WWW::GoodData::Agent instance to use.

retries

A number of retries to obtain results of asynchronous tasks, such as report exports or data uploads. See poll.

Defaults to 3600 (delay of one hour).

Traverse the links in resource hierarchy following given PATH, starting from API root ("gdc" by default).

PATH is an array of dictionaries, where each key-value pair matches properties of a link. If a plain string is specified, it is considered to be a match against category property:

  $gdc->get_links ('md', { 'category' => 'projects' });

The above call returns a list of all projects, with links to their metadata resources.

get_uri PATH

Follows the same samentics as links() call, but returns an URI of the first matching resource instead of complete link structure.

login EMAIL PASSWORD

Obtain a SST (login token).

logout

Make server invalidate the client session and drop credential tokens.

Is called upon destruction of the GoodData client instance.

projects

Return array of links to project resources on metadata server.

delete_project IDENTIFIER

Delete a project given its identifier.

create_project TITLE SUMMARY

Create a project given its title and optionally summary, return its identifier.

reports PROJECT

Return array of links to repoort resources on metadata server.

compute_report REPORT

Trigger a report computation and return the URI of the result resource.

export_report REPORT FORMAT

Submit an exporter task for a computed report (see compute_report), wait for completion and return raw data in desired format.

ldm_picture PROJECT

Return picture of Logical Data Model (LDM) in PNG format.

ldm_manage PROJECT MAQL

Execute MAQL statement for a project.

upload PROJECT MANIFEST

Upload and integrate a new data load via Single Loading Interface (SLI).

poll BODY CONDITION

Should only be used internally.

Run BODY passing its return value to call to CONDITION until it evaluates to true or retries (see properties) times out.

Returns value is of last iteration of BODY in case CONDITION succeeds, otherwise undefined (in case of timeout).

DESTROY

Log out the session with logout unless not logged in.
