Publications Rest API Endpoint to Get All Publications

[sprintell]

As developer I want a publication API endpoint such that that when I send a GET request to the URL, hateoas compliant, paginated list of all publications in the database is returned in JSON Format
This new endpoint:

• is required to ensure scalability, it was wrongly designed in old APi, as publication which is a parent of studies was embedded inside studies
• It also required to avoid circular reference errors in the JSON API

{
   "pubmedId":"21041247",
   "publicationDate":"2010-11-01",
   "publication":"Am J Psychiatry",
   "title":"Genome-wide association study of suicide attempts in mood disorder patients.",
   "firstAuthor":{
  	"fullname":"Perlis RH",
  	"orcid":null,
  	"affiliation":""
   },
   "authors":[
  	{
     	"fullname":"Perlis RH",
     	"orcid":null,
     	"affiliation":""
  	},
  	{
     	"fullname":"Perlis RH",
     	"orcid":null,
     	"affiliation":""
  	}
   ],
    "_links": {
        	"self": {
          	"href": "{base_url}/v1/publications/{pubmedId}"
        	},
        	"search": {
          	"href": "{base_url}/v1/publications?study_accession_id"
        	}
     }
}

Management Rules

• Rule 1: Endpoint - /v1/publications
• Rule 2: HTTP Request Method - GET
• Rule 3: Endpoint should accept filter, and sort parameters as in /v1/publications?pubmedId=...&title=...&page=0&size=20&sort=...
• Rule 4: Search filter should be available for: title, and pubmedId
• Rule 5: Endpoint should be accessible to All

Acceptance Tests

• Given no parameter, when the front end sends a GET request to the endpoint
• Hateoas compliant list of publications is returned in JSON Format
• Given sorting, pagination, and/or some search and filter parameters
• When the front end sends a GET request to the same endpoint
• Hateoas compliant filtered list of publications satisfying the conditions in the url parameter must be returned
