JSONTagLib

A JSP tag library supporting access to various JSON constructs as tags. This is currently targeted at the V4 GitHub API.

Example V4 GraphQL request

    static String data2health_org = "organization(login:data2health) {"
    	+ "	id,"
    	+ "	login,"
    	+ "	repositories(first:100, orderBy:{field:NAME, direction: ASC}) {"
    	+ "		nodes {"
    	+ "			name,"
    	+ "			description,"
    	+ "			url,"
    	+ "			milestones(first:100) {"
    	+ "				nodes {"
    	+ "					id,"
    	+ "					title,"
    	+ "					description,"
    	+ "					dueOn,"
    	+ "					creator{login}"
    	+ "				}"
    	+ "			},"
    	+ "			repositoryTopics(first:100) {"
    	+ "				nodes {"
    	+ "					topic{name}"
    	+ "				}"
    	+ "			}"
    	+ "		}"
    	+ "	}"
    	+ "	members(first:100) {"
    	+ "		nodes {"
    	+ "			id,name,bio,email,login,avatarUrl"
    	+ "		}"
    	+ "	}"
    	+ "}";

Two fragments of the returned JSON

This first bit is the start of the returned object

{"data": {"organization": {
   "repositories": {"nodes": [
      {
         "repositoryTopics": {"nodes": [
            {"topic": {"name": "data2health"}},
            {"topic": {"name": "pea"}}
         ]},
         "name": "AcknowledgementsTagLib",
         "description": "JSP Tag library providing access to entities and relationships extracted from PubMed Central publications",
         "milestones": {"nodes": []},
         "url": "https://github.com/data2health/AcknowledgementsTagLib"
      },
      {
         "repositoryTopics": {"nodes": [
            {"topic": {"name": "data2health"}},
            {"topic": {"name": "pea"}}
         ]},
         "name": "CD2H-driveTagLib",
         "description": null,
         "milestones": {"nodes": []},
         "url": "https://github.com/data2health/CD2H-driveTagLib"
      },

This second bit is the start of the members section

   "members": {"nodes": [
      {
         "avatarUrl": "https://avatars2.githubusercontent.com/u/10997947?v=4",
         "name": "Dave Eichmann",
         "bio": "Director, U. of Iowa School of Library and Information Science",
         "id": "MDQ6VXNlcjEwOTk3OTQ3",
         "login": "eichmann",
         "email": "david-eichmann@uiowa.edu"
      },
