-# Data-Product-Specification
+# Data-Product-Specification
+
+This repository wants to define an open specification to define data products with the following principles in mind:
+- DP as an indipendent unit of deployment
+- Technology indipendence
+- extensibility
+
+With an open specification will be possible to create services for automatic deployment and interoperable components to build a dat amesh platform.
+
+
+# Data Product structure
+
+The DP is composed by a general section with DP level information and four sub-structures:
+* Environment: where the DP will be deployed, containing all the specific information of the physical environment.
+* Output Ports: representing all the different interfaces of the DP to expose the data
+* Workloads: Internal jobs/processes to feed the DP and to perform housekeeping ( GDPR, regulation, audit, data quality, etc )
+* Observability: provides transparency to the data conusmer about how the DP is currently working. this is not declarative, but exposing runtime data.
+
+Each DP Trait ( Outputport, workload, observability ) will have a well defined and fixed structure and a specific one to handle technology specific stuff.
+The fixed structure must be technology agnostic.
