  • Mapping YANG to Document Schema Definition Languages and Validating NETCONF Content
    2011
    Co-Authors: Ladislav Lhotka
    Abstract:

    This Document specifies the mapping rules for translating YANG data models into Document Schema Definition Languages (DSDL), a coordinated set of XML Schema languages standardized as ISO/IEC 19757. The following DSDL Schema languages are addressed by the mapping: Regular Language for XML Next Generation (RELAX NG), Schematron, and Schematron and Document Schema Renaming Language (DSRL). The mapping takes one or more YANG modules and produces a set of DSDL Schemas for a selected target Document type -- datastore content, Network Configuration Protocol (NETCONF) messages, etc. Procedures for Schema- based validation of such Documents are also discussed.

  • Representing Netconf Data Models using Document Schema Definition Languages (DSDL)
    2008
    Co-Authors: Rohan Mahy, Sharon Chisholm, Ladislav Lhotka
    Abstract:

    This Document describes a concrete proposal for creating Netconf and other IETF data models using the RelaxNG Schema language and the Schematron validation language, which are both part of ISO's Document Schema Definition Languages (DSDL) standard.

  • XML Schema language: taking XML to the next level
    IT Professional, 2001
    Co-Authors: A. Ramanujan
    Abstract:

    Schemas add data typing and inheritance features, giving XML the sophistication required to create enterprise-class business applications. The XML Schema language describes the legal structure, content, and constraints of XML Documents. The XML Schema language provides the necessary framework for creating XML Documents by specifying the valid structure, constraints, and data types for the various elements and attributes of an XML Document. Schema language provides enhanced as well as more comprehensive and powerful features than a Document type definition (DTD). The XML Schema language provides the rich data typing associated with ordinary programming languages. The W3C XML Schema specification defines several different built-in data types, such as string, integer, Boolean, date, and time, among others. The specification also provides the capability for defining new types. Developers can use these built-in as well as user-defined data types to effectively define and constrain XML Document attributes and element values.

  • Evaluation and Comparison of Metrics for XML Schema Languages
    'IOS Press', 2017
    Co-Authors: Falola Damilare, Misra Sanjay, Adewumi A. O., Damasevicius Robertast
    Abstract:

    The importance of XML (eXtensible Markup Language) can’t be understated; their usefulness may range from data sharing to data transport in software systems. Schema languages describe the structure of an XML Document and the common Schemas languages are Document Definition Type (DTD), W3C XML Schema and RelaxNG. Applications depend heavily on XML Documents to be free of error and this makes it imperative to determine the quality of such Schema Document. Schema metrics is used to achieve this, and several of them have been proposed in recent years. In this paper we present the existing Schema metrics and to make comparative studies on all Schema metrics, figuring out the features, advantages and limitations of each metrics

  • integrating a structured text retrieval system with an object oriented database system
    Very Large Data Bases, 1994
    Co-Authors: Jurgen Annevelink
    Abstract:

    We describe the integration of a structured-text retrieval system (TextMachine) into an object-oriented database system (OpOur approach is a light-weight one, using the external function capability of the database system to encapsulate the text retrieval system as an external information source. Yet, we are able to provide a tight integration in the query language and processing; the user can access the text retrieval system using a standard database query language. The effcient and effective retrieval of structured text performed by the text retrieval system is seamlessly combined with the rich modeling and general-purpose querying capabilities of the database system, resulting in an integrated system with querying power beyond those of the underlying systems. The integrated system also provides uniform access to textual data in the text retrieval system and structured data in the database system, thereby achieving information fusion. We discuss the design and implementation of our prototype system, and address issues such as the proper framework for external integration, the modeling of complex categorization and structure hierarchies of Documents (under automatic Document Schema impand techniques to reduce the performance overhead of accessing an external source.
