A Clojure library implementing CQRS and event-sourcing using Immutant components.

TODO show how to to use as a template

TODO add DSL for contract / domain logic?

Deploy in a Wildfly cluster in Openshift

rhc create-app $APPNAME wildfly --from-code $GIT_LOCATION

rhc create-app wf wildfly --no-git

lein do clean, immutant

cp .war to ROOT.war then scp to deployments + add ROOT.war.dodeploy /var/lib/openshift/{APP_ID}/app-root/runtime/dependencies/jbossews/webapps /var/lib/openshift/5781680e2d52716c2100006a

scp @-.rhcloud.com:~//data/

scp target/clj-cqrs.war [email protected]:~/app-deployments/2016-07-09_17-09-43.431/repo/deployments/

cp app-deployments/2016-07-09_17-09-43.431/repo/deployments/clj-cqrs.* wildfly/standalone/deployments/

TODO cmd line with set of questions to build commands + memoize

APP Assisted learning -> document import/upload + BPM/workflow + screens to advance state

Index -> category trees, documents Connectors + extractor for entities etc... Datasets - url Workflows - BPM spec? Workbooks/Cases/study/investigation Dataflow - realtime (push or pull) or batch queries
