Start with these

Level of detail
How much graphical or geometric detail a model element shows. As a project-wide numbered scale it has largely been replaced by level of development and level of information need.

Asset information requirements (AIR)
The information an appointing party needs about an asset to operate, maintain and manage it, specified so it can be delivered into the asset information model.
buildingSMART Data Dictionary (bSDD)
A free online service from buildingSMART that hosts linked data dictionaries — classifications, object types and properties published by independent organisations — for use in BIM software.
Exchange information requirements (EIR)
The information requirements that an appointing party (or lead appointed party) sets for a specific appointment: what information is to be delivered, to what standard, when, and how it will be accepted.
Information delivery manual (IDM)
A method, standardised in ISO 29481-1, for documenting which information must be exchanged between which parties at which point in an asset's life cycle, starting from a defined use case.
Information Delivery Specification (IDS)
A buildingSMART standard for writing information requirements in a form that both people and software can read, so delivered IFC models can be checked automatically.
Level of development (LOD)
A numbered scale (LOD 100–400, plus 500 in some frameworks) describing how far a model element's geometry and information have been developed — and therefore how much other team members can rely on it.
Level of information need
A framework for specifying the extent and granularity of information required for a purpose — covering geometry, alphanumeric data and documentation — so that no more and no less is delivered than is needed.
Organizational information requirements (OIR)
The information an organization needs to meet its high-level business, strategic and regulatory objectives in relation to its built assets.
Project information requirements (PIR)
The information an appointing party needs to make its key decisions during the design and construction of a particular asset.
