Entity framework'ish tool for developing .net applications using gremlin graph query language with CosmosDb

Usage ( core)



Add the generated entity implementations to the IOC container (I will provide an extention method to make this easier)

 services.AddEntityBinding((entityType, entityImplementation) => services.AddTransient(entityType, entityImplementation))
        .AddScoped<IGremlinLanguageConnector>(s => new CosmosDbLanguageConnector(DbAccountName, AccessKey, "databaseName","collectionName"));

Defining the model

public interface IPerson : IVertex
    string Id {get;}

    string FirstName { get; set; }

    string LastName { get; set; }
    string Email { get; set; }

    EpochDateTime Birthday {get;set;}//Wrapper type for DateTime that serializes into unix epoch. Can be used in predicate steps directly.

    IEdgeCollection<IPerson> Parents { get; }

    IEdgeCollection<IPerson> Children { get; }

    IEdgeCollection<IPerson> Siblings { get; }

    [EdgeLabel("city")] //pointing to the Residents property in ICity
    IEdgeReference<ICity> HomeCity { get; }//use IEdgeReference to enable task-async operations

    IEdgeCollection<ICompany> Employers { get; }

public interface ICity : IVertex
    string Id { get; }

    string Name { get; set; }

    string ZipCode { get; set; }

   [ReverseEdgeLabel("city")] //pointing to the HomCity property in IPerson
    IEdgeCollection<Iperson> Residents { get; } //use IEdgeCollection to enable task-async operations on the collection

    IEdgeReference<ICountry> Country { get; }

public interface ICompany : IVertex
    string Id { get; }

    string Name { get; set; }

    IEdgeCollection<ICompany> Employees { get; }

public interface ICountry : IVertex
    string Id { get; }

    string Name { get; set; }

    string CountryCode { get; set; }

    string PhoneNoPrefix { get; set; }

    IEdgeCollection<ICity> Cities { get; }

    public interface IEmployment : IEdge<IProfile, ICompany>
        string Id { get; }

        EpochDateTime HiredDate { get; set; }

        string Manager { get; set; }

Defining the entity context and generating the entity implementations

public class MyEntityContext : Stardust.Paradox.Data.GraphContextBase
    public IGraphSet<IPerson> Persons => GraphSet<IPerson>();

    public IGraphSet<ICity> Cities => GraphSet<ICity>();

    public IGraphSet<ICountry> Countries => GraphSet<ICountry>();

    public IGraphSet<ICompany> Companies => GraphSet<ICompany>();

    public IGraphSet<IEmployment> Employments => EdgeGraphSet<IEmployment>();

    public MyEntityContext(IGremlinLanguageConnector connector, IServiceProvider resolver) : base(connector, resolver)

    protected override bool InitializeModel(IGraphConfiguration configuration)
        //Added some fluent configuration of the edges
                .AddEdge(t => t.Children, "children").Reverse<IPerson>(t => t.Parents)
                .AddEdge(t => t.Employees, "employees").Reverse<IPerson>(t => t.Employers)
        return true;

Using the datacontext

public class DemoController:Controller
    private MyEntityContext _dataContext;
    public DemoController(MyEntityContext dataContext)

    public Task<IActionResult> GetDataAsync(string personId)
        var person=await _dataContext.Persons.GetAsync(persionId);
        return new User

    public Task<IActionResult> AddEmploymentAsync(string userId, string companyId,DateTime hiredDate, string managerName) //new in V2
        var user=await await _dataContext.Persons.GetAsync(persionId);
        var company=await _dataContext.Companies.GetAsync(companyId);
        var e= _dataContext.Employments.Create(user,company);
        await _dataContext.SaveChangesAsync();

    public Task<IActionResult> AddEmploymentAlternativeAsync(string userId, string companyId,DateTime hiredDate, string managerName) //edge property handling in V1
        var user=await await _dataContext.Persons.GetAsync(persionId);
        var company=await _dataContext.Companies.GetAsync(companyId);
        user.Employers.Add(company,new Dictionary<string,object>{
        await _dataContext.SaveChangesAsync();

Dynamic graph entities

In many cases we cannot model our graph as strong typed entities. Paradox supports hybrid entities by adding IDynamicGraphEntity to your edge or vertex definition you can model the well known peroperties on your entities, but at the same time assign and manipulate arbitary properties. These properties enjoy the same treatment as the typed properties with regards to parameterization and change tracking.

    public interface IProfile : IVertex, IDynamicGraphEntity
        string Id { get; }

        string FirstName { get; set; }

        string LastName { get; set; }

        string Email { get; set; }

        bool VerifiedEmail { get; set; }

        string Name { get; set; }

        string Ocupation { get; set; }

        DateTime LastUpdated { get; set; }

        IEdgeCollection<IProfile> Parents { get; }

        IEdgeCollection<IProfile> Children { get; }

        IEdgeReference<IProfile> Spouce { get; }

        ICollection<ICompany> Employers { get; }

        IEdgeCollection<IProfile> Siblings { get; }

        ICollection<string> ProgramingLanguages { get; }

        IEdgeCollection<IProfile> AllSiblings { get; set; }

        bool Adult { get; set; }
        string Description { get; set; }
        int Number { get; set; }
        string Pk { get; set; }
        EpochDateTime LastUpdatedEpoch { get; set; }


 var profile = await tc.VAsync<IProfile>("myId");
