PSD2 is very important and rather complicated document. It consists of 117 Articles, more than 40 definitions and lots of the related paragraphs. So whole PSD2 includes hundreds of important portions of information - semantic entities: definitions, principles, rules, relations, procedures, ...
If you want to find something, you can use .pdf or .html version and suffer from searching process. You probably very quickly will see some complexity barrier between PSD2 and you, as reader. The aim of the structured version of the PSD2 (in the form of semantic tree) is to remove mentioned barrier.
Structured version helps to answer the question: what is important in the PSD2 and where is it?
If something is important, it hase own node, name, if unnamed (suitable for search) and proper place in the tree. We know, where every term of PSD2 is defined or specified. You can quickly find what you need and see results in visual form. So also non-experts have chance to work with this Regulation.
Search in more structured documents
Suppose that you daily are using documents such as PSD2, GDPR and also TEU and TFEU, some reffered Directive or Regulations or other international treaties. Search in the 10 .pdf together is really challenge. If you have structured documents, as you can search in 1 document, same you can do search in 10 documents together. We are preparing all most the important EU documents and international treaties in structured form.
