1. Project name

EPI – Economic and legal information (

2. Short characteristic of the project

  • web portal having three basic sources of content
    • Low system containing legal rules of Collection of Laws, judgments and expert literature in a unique interconnection.
      complete Business Journal
    • complete Tendering Journal, Official Journal „S“
  • daily updated, perfect searching, wealthy opportunities if personalization

  • but first of all, the demand of clients for information having digital form was in 2001 the reason to the tender, in which our company, AION CS, s.r.o., defeated our opponents of high-sounding names.


5. Time of realization

  • 2002-2004: preparing both the content and the application
  • 2004-2007: the first version operates
  • 2008-now days: completely innovated second version
  • the commercial success of the project creates a base to the next expansion of the structured content and the implementation on the most recent technologies

6. Position on the market

  • according to Google Analytics in the year of 2008, more than 550 thousands distinct visitors, during more than 1.5 millions of visits, displayed more than 10 millions of pages

  • .NET FrameWork 3.5
  • Tovek server

10.2. Hardware

  • server farm Dell
  • Totally 2 TB of disk capacity 16 GB RAM, 10 processors

11. Solution description

EPI project is based on perfect symbiosis of the content and the form, that is data and technologies which provide their transfer to users.

11.1. Pillars

  • wide and unique information sources
  • exhaustive data model 
  • rich set of metadata 
  • XML and .NET platform 
  • excellent and highly efficient search engine
  • splendid team of programmers 
  • ideal cooperation on the client side 
  • good ideas
  • automation of routine editor tasks wherever  it is at least in some measure possible

11.2. Some principles

11.2.1. Legal system

  • decomposition of documents of primary low, that is of all regulations in Collection of Laws, into fragments/beads (more than 10 millions) where the bead is the smallest independently addressable unit (article, paragraph, letter)
  • synthesis of selected fragments into real tree-oriented groups/views, for example into consolidated readings or thematic quantities (analogy with stringing of beads on the thread)
  • linkage of fragments of legal documents, or of groups of such fragments, between each other in both directions with the help of theme-dependent links (more than 1 million)
  • documents of secondary law, that is judgments, terminology, expert literature both periodical and monothematic, is linked to legal regulations in analogical way
  • thematic sorting of both documents and their parts according to taxonomies, thesauruses and controlled dictionaries 
  • data model of low system is fully compatible with famous schemas of Metalex and Formex

11.2.2. Three-layer architecture

1st layer: Creation and administration of the content
2nd layer: Index services (both full text and controlled dictionaries)
3th layer: Presentation (searching, viewing) and personalizing services

12. Analytical works and project realization

As an introduction into EPI project, the analysis was provided in two phases. With the respect of rule “content first, the form is its shape”, sources were analyzed first, amid the form of content which was to be published on EPI portal by our client.

In this scope, it was about technical analysis

  • of digital and printed archives
  • of used processes of digital publishing in all departments/redactions of our client and their technical and personal support

with the goal to find procedures, formats and structures of used metadata, what could be used and what was necessary to add, which additions were possible to made automatically, semi automatically and manually, and also qualified guesses of necessary personal, time and financial resources.

Collecting source materials, we found the following maxim: “To make things simple is really complicated.” :)

Once our analysis of content and processes of its creation had been accepted, the solution architecture design followed amid the definition of technological realization of future processes. The result was the basic project attributes definition. In other words, what and in which time and in which price would be realized.

Our client accepted those attributes only after their hard defense. The customer left nothing without answer, searching for reasons and solutions whenever something was unclear.

What followed was the project formulation. It was then when we built three-tier project architecture, software properties, database structures, stored procedures, concepts and appearance of the user interface; we also designed distinct phases of the project and the way how the client workers would cooperate.

The next stage was the project realization. The way how the project was being build was determined by the difficulty of the project: agile programming techniques with permanent presence of our client, a transformation of task-centered programming into value-centered programming and finally the fact that the client of the system which was being built was all the time in the center of our attention.

Measured from the instance when the agreement was signet until the web was launched, the system development lasted two hard years. The EPI project was started on May 1st, 2004 (alongside with the magnificent extension of the European Union).

Commercial success of the project enabled its endured expansion by adding new content modules and techniques to accomplish them.  In the year of 2007, the whole portal was completely refined. Now the preparation of the marvelous qualitative redesign and properties expansion expected in the next year is under way; the motive of that will be the considerable usage of semantic web techniques with the help of Topic Maps techniques and approaches.
