Path-Oriented Queries and Tree Inclusion Problem

With the rapid advance of the Internet, management of structured documents such as XML documents has become more and more important (Marchiori, 1998). As a simplified version of SGML, XML is recommended by W3C (World Wide Web Consortium, 1998a; World Wide Web Consortium, 1998b) as a document description meta-language to exchange and manipulate data and documents on the WWW. It has been used to code various types of data in a wide range of application domains, including a Chemical Markup Language for exchanging data about molecules, the Open Financial Exchange for swapping financial data between banks and banks and customers, as well as a Geographical Markup Language for searching geographical information (Bosak, 1997; Zhang & Gruenwald, 2001). Also, a growing number of legacy systems are adapted to output data in the form of XML documents.

Guidelines for the use of the Internet by IUPAC bodies

_The rapid development of the Internet as a major communication tool between scientists has led to the need for a co-ordinated IUPAC presence. Many diverse groups have already initiated distribution of IUPAC related material via their Web sites. These guidelines will provide the structure on which the official IUPAC Internet site maintained through the Secretariat will be based. Rules governing the interaction between this central site and various sites operated by other IUPAC bodies are published here as well as guidelines for the operation of sites maintained by other bodies which contain IUPAC related information. The need for special care when making provisional recommendations widely available on the Internet will be emphasized.INTRODUCTIONWWW.IUPAC.ORGLocationContentElectronic publicationINTERNET HOMEPAGE DESIGN - SOME DO'S AND DON'TSBasic principlesSome do's and don'tsRECOMMENDATION TO USE CHEMICAL MULTIPURPOSE INTERNET MAIL EXTENSIONS ON IUPAC INTERNET WEBSITESMultipurpose Internet mail extensionsChemical MIMECHEMICAL MARKUP LANGUAGEGLOSSARY
