Cross-context semantic document exchange is the process of representing, editing, and transmitting a semantic document in one context, and then receiving and interpreting it in another. It is an important research topic in semantic web, e-commerce and artificial intelligence. The current research methods of semantic document exchange generally include standardization, ontology modeling and collaboration templates, each of which has its own limitations. Based on Tabdoc, any semantic document used for interaction has the same syntax, conceptual meaning, and semantic relationship, regardless of context differences. The new method has been implemented in the SDF Tabdoc based on the XML format. By applying SDF Tabdoc, the Tabdoc editor has been designed and implemented to edit any context-independent document templates and document instances. Finally, the effectiveness of the proposed method is proved by case studies and experiments, indicating that any semantic document can be consistently understood between the parties.
