Types of IETP

There are currently 4 types of IETP with a new class due to be implemented with Change 9 of the AECMA 1000D standard. The AECMA 1000D Classes of IETM 3 to 5 correspond to IETP-Linear (IETP-L), IETP-Database (IETP-D) and IETP- Integrated (IETP- I).

• IETP-L - this is a linear IETP that takes the source data from the CSDB and builds a linear document. It is desirable, but not required, to include the use of interaction attributes for facilitated interactive presentation.

• IETP-D - the IETP-D has its basis in a database which is queried, thus allowing access to the underlying Data Modules. The data can be presented through a standard linear publication construct or as query, e.g. "give me all Data modules pertaining to the engine system".

• IETP-I - the IETP-I takes the Database concept further and allows queries to and from external applications, the most common scenario is when carrying out a repair, a message is sent to the stores computer relaying the spares usage. The stores computer would then use this as a trigger to order stock.

• IETP- H - this IETP uses HTML as an output mechanism. Web Delivery will allow HTML files converted from AECMA SGML to be transferred across an Intranet environment.
  
  To be added with Change 9

• IETP-X - XML based IETP.
