Creating ECL Component using Core Service

Question

I'm trying to replace all the multimedia items uploaded in Tridion for same images stored in an External Content Repository.

We made a WS that we call with the name of the image stored in tridion (f.e. "zzz.jpg") and it returns a XML with the same data that we are receiving in our ECL Provider. With this info, we want to create a new ECL Component in Tridion using Core Service and replace the original multimedia component for the new created.

But I don't know how to create it. I tried to "copy" a stub component created with the ECL provider, but in the url, I saw a .ecl file and I don't know how I can generate it.

Any idea?

Thank you!

Answer 1

You should not attempt to create stubs manually though the core service.

The EclService (hosted in the same process as the Core Service) expose the method:

public IDictionary<string, string> CreateOrGetStubUris(IEnumerable<string> eclItemUris)

It will create the Tridion stub components for you (if needed) and return the TCM URIs.

The EclService is a WCF SOAP service like the Core Service, and you can find a generated .net client in your Tridion installation - or create your own client.

Answer 2

To respond Rahul's comment, I used this:

IEclSession eclSession = SessionFactory.CreateEclSession("MTSUser");
String eclItemID = "ecl:" + pubId + "-bccf-" + hImg.image.id + "-bchi-file";
tcmUri = eclSession.GetOrCreateTcmUriFromEclUri(eclSession.HostServices.CreateEclUri(eclItemID));

You have to build an eclItemID that matches with the integration that you made for ECL.
