Updated Feb 20, 2020, to align with Paper A11 - original June 20, 2016 (download), modified Nov 29 and Jun 20, 2019.

The Information Taxonomy (previously Project Information Taxonomy) extends the Modular Requirements Clarification Language first introduced in Paper A10. The taxonomy currently includes concepts/terms to be used in defining information requirements within mission-critical documentation (e.g. within an Employer’s Information Requirements (EIR), a BIM Management Plan (BMP) or similar).

The term ‘information’ – here used to describe Digital Assets - can be subdivided into three Information Representation Types or ‘digital artefacts’- documents, models, and data:

• Document: A medium (e.g. an email, web page, or a PDF document) carrying a variety of information including text, metadata, or embedded 3D models. A document refers to “information and its supporting medium” [i.e. when the information is placed within a medium, it becomes a document] ….“the medium can be paper, magnetic, electronic or optical computer disc, photograph or master sample, or a combination thereof” (ISO, 2009, Item 4.5), adapted from ISO (2015, Item 3.7.2). In this study, the term Document will refer to a digital medium or an analogue medium to be digitised in preparation for management and utilisation. When referring to non-digital documents, the term will be qualified (as in paper document). Examples of Documents include a Master Plan Drawing, a Performance Certificate, and an Audit Report;
• Model: A “representation of a system that allows for investigation of the properties of the system” (ISO, 2016). As a term, it may refer to digital models (e.g. shell/boundary or solid geometry graphical models); physical models (e.g. a sandcastle, LEGO model, or 3D printed shapes); or financial, mathematical, and conceptual models. In this study, unless qualified, the term Model will refer to a three-dimensional digital medium carrying a variety of information and – potentially - embedding or referencing both Documents and Data sets. A Model can represent a discipline/specialty (e.g. architectural model), a state (e.g. record model), or a base technology (e.g. object-based model); and
• Data: A digital sequence of symbols – typically letters and numbers - that can be collected and parsed/ interpreted by an actor. Data may be statically embedded within Documents and Models or drive their dynamic generation/ modification - adapted from ISO/IEC (2015). Data can be captured through sensors, actuators, and scanners (Gubbi, Buyya, Marusic, & Palaniswami, 2013); derived from connected data sources; or generated through machine learning. The term Data may be coupled with other terms preceding it (e.g. structured, unstructured, or meta-Data) or following it (e.g. Data cloud, object, routine, script, set, or table) to indicate either functional groupings, relationship structures, internal cohesion, semantic inferences, coded computer instructions, or ‘as a variety of charts and diagrams’ (Sowa & Zachman, 1992). In this study, and unless qualified, the term Data will refer to digital computable data. Data sourced from analogue devices (e.g. liquid thermometers and legacy imaging equipment) need to be digitised before it can be utilised and managed.

This representational subdivision is utilitarian and is intended for practical purposes: allow more accurate identification of targeted digital deliverables and – as illustrated in the Information Taxonomy below – provide flexibility in specifying information delivery uses, views, view definitions, viewers, and environments

This post is part of the BIMe Initiative Integrated Information Platform project and contributes to the ongoing effort to clarify the language used (or to be used) in defining project requirements within Noteworthy BIM Publications. Some of the concepts introduced above are still being refined, connected and reconnected to multiple models, taxonomies and classifications. For an up-to-date description of these concepts and their relations, please refer to respective terms within the BIM Dictionary.

[1] A document refers to “information and its supporting medium” [i.e. when the information is placed on a medium, it becomes a document] … “The medium can be paper, magnetic, electronic or optical computer disc, photograph or master sample, or a combination thereof” – [SOURCE: ISO 14050:2009, 4.5 - adapted from ISO 9000:2005, 3.7.2]

[2] Another definition is a “representation of a system that allows for investigation of the properties of the system” [SOURCE: ISO 29481-1:2016(en) Building information models — Information delivery manual — Part 1: Methodology and format]

[3] “a reinterpretable representation of information in a formalized manner suitable for communication, interpretation, or communication, or processing” [SOURCE: ISO/IEC 2382-1:1993, Information technology — Vocabulary — Part 1: Fundamental terms.01.01.02]

[4] Note: Documented Project Information should not be confused with Documented Information which is defined in ISO 9001:2015 as meaningful data that is required to be controlled and maintained by the organization and the medium on which it is contained (Source: ABP Consultant)
