The term used in relation with management of the progression and uses of information.
There is general confusion with the use of the term, due to range of other interrelated terms often used without due explanation.
Level of information is related to:
- Level of Information
- Level of Accuracy
- Level of Coordination
- Level of Granularity
The ISO 19650 framework intending to clarify the terminology in 2018 introduced a new term: ‘Level of information need’ which was designed to replace the terms used in BS EN 1192 such as Level of model definition/level of detail (LOD) and level of information (LOI)
Nevertheless, the use of the acronym LOD, caused significant confusion, even within academic papers and although the level of information need, is the better-suited description the industry needs time to update the currently available systems and standards hence we will continue to see the acronyms LOD & LOI for some time, thus to avoid further misunderstanding the acronyms shall be used with caution and always used the full name and source in the opening context.
Fortunately long awaited guidance has been recently published by BSI, BS EN 17412‑1:2020 hoping to clarify the situation
History of the term Level of
OGC City Geography Markup Language (CityGML) Encoding Standard – (OGC) – sets out 5 Levels of Detail (LoD) for 3D geospatial models, which go from LoD0 to LoD4. LoD0 is a simplified 2D building footprint, and the scale goes right up to LoD4 which includes building internal rooms and installations. 
Danish Information levels – built upon the principle of evolving detailing with the degree of detailing from level 0 to 6 
BS 1192:2007, superseded by BS 1192:2007+A2:2016. Introduced Level of model definition, level of detail (LOD) and level of information (LOI) 
301 – Building Information Modeling (BIM) Addendum – include term Level of Development (LOD). It is a US Industry alternative to the AIA digital practise documents. References the BIMForum LOD Specification 2015 as part of its MPS. 
E203TM, G201TM & G202TM – establish Model Management Protocols and Processes, Level of Development (LOD), Model Authorised Uses, and provides a Model Element Table matrix. AIA E202TM 2008 BIM Protocol Exhibit used the Vico’s MPS Level of Detail schema but changed it to Level of Development; LOD 100, LOD 200, LOD 300, LOD 400 & LOD 500. AIA coined the term Level of Development (LOD). It has become the benchmark when it comes to comparing MPS schemas. 
Minimum Modelling Matrix (M3) similar to the AIA G202TM 2013 definitions. This Progression Management system uses (Level of Development) LOD 100, LOD 200 & LOD 300, but, also, has a grade classification suffix attribute when specifying design model elements for construction documents. It also has an additional suffix symbol for an As-Built status. The scheme does not engage LOD 400 or LOD 500.
National Guidelines for Digital Modelling – It guides Model development phases (taken from BIPs 2007). These are from Phase 0 to 6. Phase 1 being: Briefing/Pre-design, 2; Conceptual design, 3; Schematic design, 4; Developed design, 5; Contract documents, and 6; Post-construction/Facilities management. It uses terms such as Level of Detail (LOD)
