Bypass Model dependency while indexing data in ElasticSearch

Based on the feedback given in SDL Web Dev Summit in Delhi,India.

This is in continuation of my previous blog where we have used ElasticSearch as storage while publishing components data is getting saved in it.

Earlier whenever we need to index any component we first need to create schema model,that creates model based dependency to bypass that we now Serialize the DCP (Dymanic Component preseatation)which is in XML format into JSON and Elastic Search .NET based NEST API has this capability to index JSON directly.

Now, we just need to allow the schema in Dynamic Component Template which we have created to index the data in ElasticSearch.

In NEST API we have used

         var json = @"{
    ""BookName"": ""Book1"",
    ""ISBN"": ""978-3-16-148410-0"",
    ""chapter"" : [
        {
            ""chapter_name"": ""Chapter1"",
            ""chapter_desc"": ""Before getting into computer programming, let us first                     understand computer programs and what they...""
        },
        {
            ""chapter_name"": ""Chapter2"",
            ""chapter_desc"": ""Today computer programs are being used in almost every field,               household, agriculture, medical, entertainment, defense..""
        },
        {
            ""chapter_name"": ""Chapter3"",
            ""chapter_desc"": ""MS Word, MS Excel, Adobe Photoshop, Internet Explorer,                     Chrome, etc., are...""
        },
        {
            ""chapter_name"": ""Chapter4"",
            ""chapter_desc"": ""Computer programs are being used to develop graphics and                   special effects in movie...""
        }
    ]
}";

var indexResponse = client.LowLevel.Index<string>("fromelasticstoweb8", "esnews", json);


And Link Resolver TBB is used to generate the Link e;g i have multimedia component attached ,when you published it will resolve the link below is the DCP XML.

Mircoservice over SDL WEB 8 Coreservice


Self Hosted REST Microservice using OWIN and ASP.NET Web API 2

Open Web Interface for .NET (OWIN) defines an abstraction between .NET web servers and web applications. OWIN decouples the web application from the server, which makes OWIN ideal for self-hosting a web application in your own process, outside of IIS.

ASP.NET Web API - CORS Support in ASP.NET Web API 2. Cross-origin resource sharing (CORS) is a World Wide Web Consortium (W3C) specification (commonly considered part of HTML5) that lets JavaScript overcome the same-origin policy security restriction imposed by browsers.

For more details on how to setup and create Microservice read it here.

This service is used to get the data from SDL WEB 8 CM Database
