Since
tourism information can often be stored in flat files, dynamic packaging applications
need to include methods to integrate these data into a common data model.
This requires the development of specific software application modules to access
and extract the necessary data.
Hyper.Text.Markup.Language
With the growth of the Web, many tourism information providers already have Web
sites for storing and advertising the description of tourism services and products.
Almost all Web sites support static HTML pages accessible through a Web server via
the HTTP protocol. Dynamic packaging applications require integrating Web-based
data sources in an automated way for querying, in a uniform way, across multiple
heterogeneous Web sites, containing tourism-related information.
Extensible.Markup.Language
XML (XML, 2005) is a semi-structured data model that promises to accelerate the
construction of systems that integrate distributed and heterogeneous data. XML
provides a common format for data across the network and is being supported by
a vast number of data management tools.
