The EDI Primer
For those who may be unfamiliar with the EDI standard, and those who may have used EDI but have encountered a new, unfamiliar question.
This introduction aims at addressing the basic questions of convention and implementation of the EDI technology. I have a list of topics, and hope that over time I can cover all of them. I also hope that people reading here may have questions that I haven’t thought to write about. Please let me know what your questions are and I will see what I can do about providing answers.
- What is EDI?
- Parts of EDI
- Segments
- Delimiters
- Conventions of EDI
- Why are there more than one version of EDI?
- Standards and Usage
- Encoded Values
- EDI in Good Form
- Element Notation
- Wrapped and Unwrapped EDI
- Enveloping Part One
- Enveloping Part Two – ISA
- Enveloping Part Three – GS
- Enveloping Part Four – ST
- Loops in EDI
- Hierarchical Levels
Of course understanding how EDI presents and represents data is the first step. From here we may want to go to our Data Mapping Guide, or if we are familiar with mapping there are some examples in our mapping case studies of EDI to and from other formats. Again, if you have an interesting problem or solution, I would love to here about it. Please send it to
roy@TheIntegrationEngineer.com and I will see what I can do.
