Building Semantic Trees from XML Documents
2016
International audience; The distributed nature of the Web, as a decentralized system exchanging information between heterogeneous sources, has underlined the need to manage interoperability, i.e., the ability to automatically interpret information in Web documents exchanged between different sources, necessary for efficient information management and search applications. In this context, XML was introduced as a data representation standard that simplifies the tasks of interoperation and integration among heterogeneous data sources, allowing to represent data in (semi-) structured documents consisting of hierarchically nested elements and atomic attributes. However, while XML was shown most …
Building Ontologies from XML Data Sources
2009
In this paper, we present a tool called X2OWL that aims at building an OWL ontology from an XML datasource. This method is based on XML schema to automatically generate the ontology structure, as well as, a set of mapping bridges. The presented method also includes a refinement step that allows to clean the mapping bridges and possibly to restructure the generated ontology.
Extensible User-Based XML Grammar Matching
2009
International audience; XML grammar matching has found considerable interest recently due to the growing number of heterogeneous XML documents on the web and the increasing need to integrate, and consequently search and retrieve XML data originated from different data sources. In this paper, we provide an approach for automatic XML grammar matching and comparison aiming to minimize the amount of user effort required to perform the match task. We propose an open framework based on the concept of tree edit distance, integrating different matching criterions so as to capture XML grammar element semantic and syntactic similarities, cardinality and alternativeness constraints, as well as data-ty…
XCDL: an XML-oriented visual composition definition language
2010
International audience; XML data flow has reached beyond the world of computer science and has spread to other areas such as data communication, e-commerce and instant messaging. Therefore, manipulating this data by non expert programmers is becoming imperative. On one hand, Mashups have emerged a few years ago, providing users with visual tools for web data manipulation but not necessarily XML specific. Mashups have been leaning towards functional composition but no formal languages have yet been defined. On the other hand, visual languages for XML have been emerging since the standardization of XML, and mostly relying on querying XML data for extraction or structure transformations. These…
Adopting XML for Large-Scale Information
2011
This book has presented many different ways to encode information in XML format and the purposes for doing so. In this concluding chapter we consider problems related to managing XML information assets and the methods available to address those problems. Approaches for persistently storing XML data can be divided into file storage and database storage, and the research community has been especially active in designing new solutions for XML databases. However, adoption of XML often means massive migration procedures from some legacy data into the XML format; examples of migration cases are given. While describing the problems related to adopting XML, we give examples of the kinds of data fo…
Why Use XML?
2011
Since its inception a decade ago, XML has become a standard technology for software engineers, all Web browsers are able to parse and show XML documents, and huge XML data resources are available from the Internet. Many of the documents are in XHTML, but other XML applications are quite common as well. XML has also become a format that is increasingly common in the files of local disks. This success would not have been possible without collaborative efforts throughout the Web community. Such world-wide collaborative development has included standards, software applications, and case implementations that can serve as models when developing new solutions. In this chapter we consider what ki…
