 * `Status: [Option[String]]` this is an enum representing the status of this version of the Data Product. Allowed values are: `[Draft|Published|Retired]`. This is a metadata that communicates the overall status of the Data Product but is not reflected to the actual deployment status.
 * `Maturity: [Option[String]]` this is an enum to let the consumer understand if it is a tactical solution or not. It is really useful during migration from Data Warehouse or Data Lake. Allowed values are: `[Tactical|Strategic]`.
 * `Billing: [Option[Yaml]]` this is a free form key-value area where is possible to put information useful for resource tagging and billing.
-* `Tags: [Array[Yaml]]` free tags at Data Product level (please refer to OpenMetadata https://docs.open-metadata.org/openmetadata/schemas/entities/tagcategory).
+* `Tags: [Array[Yaml]]` Tag labels at DP level ( please refer to OpenMetadata https://docs.open-metadata.org/metadata-standard/schemas/types/taglabel).
 * `Specific: [Yaml]` this is a custom section where we can put all the information strictly related to a specific execution environment. It can also refer to an additional file. At this level we also embed all the information to provision the general infrastructure (resource groups, networking, etc) needed for a specific Data Product. For example if a company decides to create a ResourceGroup for each data product and have a subscription reference for each domain and environment, it will be specified at this level. Also it is reccommended to put general security here, Azure Policy or IAM policies, VPC/Vnet, Subnet. This will be filled merging data defined at common level with values defined specifically for the selected environment.
 
 The **unique identifier** of a Data Product is the concatenation of Domain, Name and Version. So we will refer to the `DP_UK` as a URN which ends in the following way: `$DPDomain:$DPName:$DPMajorVersion`.

   * `IntervalOfChange: [Option[String]]` how often changes in the data are reflected.
   * `Timeliness: [Option[String]]` the skew between the time that a business fact occuts and when it becomes visibile in the data.
 * `Endpoint: [Option[URL]]` this is the API endpoint that self-describe the output port and provide insightful information at runtime about the physical location of the data, the protocol must be used, etc.

 * `SampleData: [Option[Yaml]]` provides a sample data of your Output Port. See OpenMetadata specification: https://docs.open-metadata.org/openmetadata/schemas/entities/table#tabledata
 * `Schema: [Array[Yaml]]` when it comes to describe a schema we propose to leverage OpenMetadata specification: Ref https://docs.open-metadata.org/metadata-standard/schemas/entities/table#column. Each column can have a tag array and you can choose between simples LabelTags, ClassificationTags or DescriptiveTags. Here an example of classification Tag https://github.com/open-metadata/OpenMetadata/blob/main/catalog-rest-service/src/main/resources/json/data/tags/piiTags.json.
 * `SemanticLinking: [Option[Yaml]]` here we can express semantic relationships between this output port and other outputports (also coming from other domains and data products). For example we could say that column "customerId" of our SQL Output Port references the column "id" of the SQL Output Port of the "Customer" Data Product.

 * `WorkloadType: [Option[String]]` explains what type of workload is: Ingestion ETL, Streaming, Internal Process, etc.
 * `ConnectionType: [Option[String]]` an enum with allowed values: `[HouseKeeping|DataPipeline]`; `Housekeeping` is for all the workloads that are acting on internal data without any external dependency. `DataPipeline` instead is for workloads that are reading from outputport of other DP or external systems.

Output Ports are identified with `DP_UK:$OutputPortName`, while external systems will be defined by a URN in the form `urn:dmb:ex:$SystemName`. This filed can be elaborated more in the future and create a more semantic struct.
