cics graphql support

On this years CAF you told us the future of the CMCI interface would be a graphql interface.

After some investigations I now clearly see the advantage of this form of requests.

So I would like to have a possibility for PL/1 / Cobol to do the same.

As you already did this with JSON/REST I think you could do the same easily for graphql with the already adopted mechanism for REST/Json with the bind files.

I would suggest to add this to your cics explorer hill for cics venus, as I think this is the future of webservices.

    We have assessed this requirement. We have no current plans for this to be implemented and so this requirement is being declined at this point. The requirement will be kept in the RFE system and might be reassessed in the future. You also have an opportunity to resubmit in twelve months time if you wish it to be reconsidered then.

    Hi cics team!

    We are currently evaluating zos connect and maybe this is better place for graphql support.

    zos connect is already doing a mapping and maybe lots of this stuff can be just recycled to build a graphql api.

    If i look to cobol/pl1 structures I think they fit much more to graphql than to rest, because you have a lot of data, but you normally only want a bit out of it, so I definitely think this is the way to go here.

    If we buy zosconnect, I would definitely prefer to have graphql support in there, but I am only one customer.

    I have opened an RFE for this.

    Thanks

    Hi Peter, thanks for your interest in this area!

    As you'll have noticed from your research, GraphQL differs markedly from REST, in having a single endpoint and having a strongly-formed schema.

    As such, we can see that there would have to be a very different way of setting up CICS web support with GraphQL instead of REST. It would require a lot more user input in order to determine how the schema was constructed, for example. As such, it's very unlikely that we'll start looking at this in the Venus timeframe.

    However, there's nothing to stop you using GraphQL server libraries in CICS to create and serve your own GraphQL endpoints. For example, you might use a JVM server and use graphql-java (https://github.com/graphql-java/graphql-java) to create your schema and resolve data from CICS programs, perhaps with the IBM Record Generator for Java (https://developer.ibm.com/mainframe/products/record-generator-for-java/).
