h1. Introduction

See [PLFM:Service API Design] for the rationale and design details for this api.

See [Developer Bootstrap#DeveloperBootstrap-ServiceDevelopment|PLFM:Developer Bootstrap#DeveloperBootstrap-ServiceDevelopment] for instructions on how to run a local instance of this service.

h2. Encoding

The primary request and response encoding for the service is JSON.  Here's a handy tool to make a blob of JSON more readable: [http://jsonformatter.curiousconcept.com/]

In responses from the service, dates are serialized as long integers expressing epoch time - the number of seconds elapsed since midnight Coordinated Universal Time (UTC) of January 1, 1970, not counting leap seconds.  Here's a handy tool to convert from epoch time to human readable dates: [http://www.epochconverter.com/]

In requests to the service, dates can be serialized either as long integers expressing epoch time or human readable dates in [http://www.ietf.org/rfc/rfc3339.txt |RFC 3339] format such as '2011-01-31' or '2011-01-31T22:00:00'

h2. Security

Eventually these services will be HTTPS only and disallow HTTP.  Users will pass something like _?access_token=..._ as a query parameter for every request to the service

h1. Usage Examples

This is a REST api (see [PLFM:Service API Design] for more details as to what this means).  You can create entities, updated entities, read entities, and delete entities.  More advanced querying will be implemented as a separate API. Partial updates (e.g., just updating two fields in a dataset) are not supported.  In a nutshell, when you update something like a dataset, you GET the dataset first, modify the properties you want to change, and then send the entire object back to the service so that this revised entity overwrites the previously stored entity.

h2. Get Datasets

Optional Parameters
* offset \- integer - 1-based pagination offset
* limit \- integer - maximum number of results to return
* sort - string - the name of the primary field upon which to sort
* ascending - boolean - whether or not to sort ascending

h2. Add Annotations to a Dataset

First get the empty annotations container for your newly created dataset

Request{code}
curl -i http://localhost:8080/repo/v1/dataset/agxkZWZsYXV4LXRlc3RyEwsSDUdBRUpET0RhdGFzZXQYAQw/annotations
{code}

Response{code}

   "etag":"923521",
   "stringAnnotations":{

   },
   "floatAnnotations":{

   },
   "dateAnnotations":{

   }
}
{code}

Then you add/modify the annotations of interest and do a PUT. *Note that annotation values must always be list values even if the list is only of length one.*

Request{code}
curl -i -H Accept:application/json -H Content-Type:application/json -X PUT -H ETag:923521 -d '{
