Many applications deal with highly flexible XML documents from different sources, which makes it difficult to define their structure by a fixed schema or a DTD. therefore, it is necessary to explore ways to cope with such XML documents. the paper analyzes different storage and retrieval methods for schemaless XML documents using the capabilities of relational systems. We compare our experiences withthe implementation of an XML-to-relational mapping with an LOB implementation in a commercial RDBMS. the paper concludes with a vision of how different storage methods could converge towards a common high-level XML-API for databases.

Many WWW applications generate hypertext markup language or extensible markup language (XML) documents dynamically. Current tools, however, like languages using document object model (DOM) or JAVA Server Pages do not allow to check the validity of the generated documents statically. Instead, validity has to be 'checked' dynamically by appropriate test runs. this paper addresses this problem by introducing a new distinct class for each element type of a document type definition (DTD). Each class extends the Element-class of the DOM. the resulting object model is called validating DOM (V-DOM). Parametric XML (P-XML) is an extension of XML allowing to insert values of the newly defined classes in places, where the corresponding element types are allowed according to the underlying DTD. Like V-DOM, P-XML guarantees the validity of all XML documents generated by using P-XML. V-DOM and P-XML are illustrated by several examples. (C) 2002 Elsevier Science B.V. All rights reserved.

this paper presents ARK, a minimal, XML-based configuration language and framework for our particular problem domain: UNIX System Administration. the language allows the capture of poorly structured configuration data and code fragments written in various programming languages, while the ARK engine is responsible for interpreting the XML and allowing applications to query data and invoke code fragments. the paper discusses the need for a minimal, simple approach, and provides examples which illustrate the use of the prototype-based model supported by the language. the ARK framework is currently being used to manage several academic and industrial UNIX installations.

In this paper, we present a temporal, object-oriented algebra which serves as a formal basis for the query language of a temporal, object-oriented data model. Our algebra is a superset of the relational algebra in tha...

Critical infrastructures must be able to mitigate, at run-time, suspected ongoing cyberattacks that have eluded preventive security measures. To tackle this issue, we first propose an autonomic computing architecture for a Cyber-Security Incident Response Team Intelligent Decision Support System (CSIRT-IDSS) with a precise set of technologies for each of its components. We then zoom in on the component responsible for proposing to the CSIRT, automatically ranked sets of runtime actions to mitigate suspected ongoing cyber-attacks. We formalize its task as a Constraint Optimization Problem (COP). We then propose to implement it by a Constraint object-oriented Logic Program (COOLP) deployed as a containerized web service through the integration of three orthogonal extensions of Logic programming (LP): Web Service oriented LP (WSOLP), Constraint LP (CLP) and object-oriented LP (OOLP). this integration supports seamlessly reusing platform and task independent cybersecurity ontological knowledge to dynamically build a mitigation action search COP that is customized to an input suspected cyberattack action set. this customization then allows the COP, to be solved by a generic CLP engine efficiently enough to propose mitigation actions to the CSIRT team while they can still be effective. To validate this approach, we implemented a prototype called CARMAS (Cyber Attack Runtime Mitigation Action Search) and ran scalability tests on simulated attacks with various COP construction strategies.
