Publications Rest API Endpoint to Get All Publications

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
