![]() They can be optional or required, and default or fixed values can be defined by the schema. Here is an XML element with an attribute: SmithĪnd here is the corresponding attribute definition: But the attribute itself is always declared as a simple type. If an element has attributes, it is considered to be of a complex type. It should not be confuse with ID and IDREF which are about identification and references to the identifier.Īll attributes are declared as simple types. It should be considered accordingly when deriving an OWL file from the XSD: positiveInteger, token, string, nonNegativeInteger. XML Schema has a lot of built-in data types, which are also those available for OWL Data type properties.ĪrchiMate XSD defines several simple elements, using some of these data types. You can also add restrictions (facets) to a data type in order to limit its content, or you can require the data to match a specific pattern. It can be one of the types included in the XML Schema definition (Boolean, string, date, etc.), or it can be a custom type that you can define yourself. However, the "only text" restriction is quite misleading. It cannot contain any other elements or attributes. Used XML schema constructs XML simple element and attributesĪ simple element is an XML element that can contain only text. Impacts within the application landscape and for digital continuity.Comparison between exchange schema and Archi Serialization schema.Some issues with the ArchiMate exchange schema.The different sections of the article are: This article is providing such an analysis and relates it to some encountered interoperability issues, such as the first issue exemple, the non preservation of physical breakdown of a model, with new lessons learnt and enrichment of the initial proposed draft approach, with extended set of requirements to be considered by the ArchiMate community if willing to address the identified issues. The schema provided with the Open Exchange Format for ArchiMate were not studied and the XML technologies were not exploited with what they can bring. The approach was more a "black box" approach, considering mainly what happens before and after the import/export sequences. Several kinds of issues were described, in order to illustrate what can prevent achieving interoperability. A set of test cases and associated models have been produced allowing testing solutions and preventing to encounter these issues, with a draft approach for producing these testing models. In the article about " Potential issues illustrated with practical cases with Archi, EA, Modelio", a practical approach for assessing interoperability required for digital continuity within the ArchiMate digital business ecosystem was proposed, starting from concrete examples and interoperability issues discovered from the practice. And don't hesitate reflecting my skills on my LinkedIn profile if you think it is appropriate :) Introduction If you think this article creates value, don't hesitate to share it and like it. What do we learn from exchange format schema study? (this article)ĭon't hesitate sharing you comments, knowledge, viewpoints and experience/best practices on the topic.From models to linked data using semantic web technologies?.Potential issues illustrated with practical cases with Archi, EA, Modelio.This is the third article of a series about ArchiMate Interoperability, which includes: ![]()
