Architecture Overview


The DeepaMehta 4 Software Platform is OSGi based
and implements a Microservice Architecture.

Technically DM 4 is made of Java, Neo4j, Lucene, Apache Felix (OSGi), Jetty, Jersey, Thymeleaf (optional), Neo4j Spatial (optional), Websockets (optional), Karaf (optional)

The DeepaMehta 4 Webclient brings it's own
GUI Framework enabling developers to extend it.

    DeepaMehta 4 Tags

    A module for users who interactively want to extend a "Type" of their choice about the possibilty to add many "Tags".

    This plugin started as just a (declarative) migration introducing custom types so that other plugins can rely on their existence and start building on them. 

    Tags 1.1 comes now with its own plugin-service providing simple standard queries around "Tags" to other developers.
