Description When the electronic revolution started in 1990, PDF files were used as IETM till 2000. They used to be scanned images/raster images. Searching and hyperlinking indexing were not possible in those raster images. These are called LEVEL -1 IETM.
Advancement in technology, use of OCR, and other features was added in PDF files. Thus PDF was made with selectable text, images, tables, hyperlinks, and indexing etc. Cross-references hyperlinks made PDF more interactive and user-friendly. These were called LEVEL -2.
In level -2 there was one limitation. If the user manual or PDF file is single, then LEVEL 2 worked well. Hyperlinks inside a single PDF were possible but refereeing multiple PDFs i.e. cross-reference between manuals was again a challenge. For instance, let us assume that a user is looking for troubleshooting of some device and the troubleshooting requires the user to see the operational manual and technical manual etc.
Cross referring to multiple manuals was a problem. During that time HTML 5 has very strongly emerged as technology (2012). Taking advantage of technology, all these files are converted into HTML -5 and an IETM viewer is a piece of software program developed to see the files. This is LEVEL -3.
When the documents were thousands in number and ultra-quick navigation is needed for user inputs. In this scenario LEVEL, -4 was evolved. Level -4 is Database driven software which is way ahead powerful than all the previous levels.
