Raw datasets (taxa scorings) are inputted by the user into a locked “score list template” and saved as a MS Excel sheet. Mandatory fields (marked by *) include taxa scores, geographical information (country, locality/site), stratigraphy and references quoted, e.g., original floristic studies, etc. The mandatory items are important for further “internal” database processes (there are criteria for “internal” classification of the studied objects). IPR website was rewritten in Ruby, using the Ruby on Rails framework. Data is stored in a PostgreSQL database. Website is fully administrable via a custom CMS. Updated version allows authors to easily define new vegetation types and tweak the existing ones. Sites can be added online or imported using an XLSX template. Thanks to those technologies, the “online database” page does not need to be reloaded every time a query is processed.
