CETA is really huge document. It consists of 30 Chapters (453 pages), more then 1200 pages of Annexes. CETA includes hundreds of important portions of information- semantic entities: definitions, principles, rules, relations, procedures.  

If you want to find something, you can use .pdf version and suffer from searching process. You quickly will see the complexity barrier between CETA and you, as reader.  The aim of the structured version of the CETA (in the form of semantic tree) is to remove mentioned barrier. 

Structured version helps to answer the question: what is important in the CETA and where is it?
If something is important, it hase own node, name (suitable for search) and proper place in the tree. We know, where every term of CETA is defined or specified in the CETA.You can quickly find what you need and see results in visual form. So also non-experts have chance to work with treaty.

Search in more structured documents
Suppose that you daily are using documents such as CETA and also TFEU, Protocols, Rome 1 -3, Brussels 1-2 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 of the important EU documents and international treaties in structured form.
