Linking Dapps

by

We’re happy to announce a new feature: Dapp linking.  This feature lets you links two or more Dapps together.  The ouput from the first Dapp is used as input to the second Dapp (and so on).  For instance, if you have a Dapp which takes a zip code and returns movies playing in that area, and another Dapp which takes a movie title and returns reviews, you can link the two together.  The end result is a new Dapp which, in this example, takes a zip code and returns a list of movies playing in the area and reviews of each movie.

To link two Dapps together, find the first Dapp and select “Use this Dapp” – from the next page, click “Link to Another Dapp” and you’re on your way.  As always, your feedback and bug reports are greatly encouraged.

    that’s great, i was hoping this feature would come out soon. when’s the news on increased usability though? i keep hearing people talk about Dapper but everyone agrees that usability is a HUGE issue. good luck!

    dapp link feature definitely cool, but I’m still waiting for the “create dapp from RSS” feature. I wonder if it still take sometimes before available for public ..

    Marshall: We’re definitely working on usability features. Over the past few weeks, we’ve sneaked some additional help, demos, and features into the service in hopes of making it easier to use. More substantial changes will most likely surface in the coming months.

    Toni: Creating a Dapp from RSS (and XML, CSV, and existing web services) is on the way.

    It would be amazingly cool to have a sort of “visio” style visual Dapp builder. Drag and drop output pin from one dapp to input pin of another dapp…

    Another amazingly cool thing, that might already be able to be done, but I can’t figure out how, would be to plug the output of one service into the creation of another. For example, use the HTML formatter to create the body of my RSS feed.
