Markers

As per my Glossary page, a “marker” is a special type of symbol within a context.

A marker is a symbol used within a context to represent some especially important aspect of that context.

Constructed from a specifically selected portion of the syntactic medium within a context that has special, almost self-referential meaning specifying some logical subset of data.

Markers appear in many guises, and support many different types of uses, as described in the following paragraphs. As symbols, markers consist of the typical two components: signs and concepts.

A ”Semantic Marker” is a reference to or name of a logical description of a business condition, context or process that acts as a short-hand representation for the condition.

A ”Syntactic Marker” is a physical sign which can be used to represent a Semantic Marker. It is recognized as or defined over a certain subset of the data structures and content available at a particular location in the business process. This is a marker that can be recognized by the business process itself and used to guide the process where knowing the context is important.

A ”Context Marker” is a designation of the Context, Path, Step and/or Anchor State representing a position in the business process. A marker that provides sufficient information to identify the context of an action or state.

A ”Process Marker” is a marker that represents a process itself. It can be used to retrieve run-time parameters, or to record performance and status metrics.

An ”Option Marker” is a marker that does not by itself specify a context but which can specify the proper variation or logic path of a derivation. Generally, an option marker represents a condition, a subset, perhaps a decision or event, within a context that should be remembered later in a process.

An ”Explicit Marker” is any syntactic marker designed from the beginning to act specifically as a marker.

An ”Implicit Marker” is any marker implied by the context directly. For example, using the assumption that any data coming through a transformation are by definition within a certain context. Hence the mere existence of data in the process acts as a marker for the process. Only context-sensitive derivations/transformations can use implicit markers.

A ”Derived Marker” is a marker interpreted or derived from other data, not necessarily pre-defined as a marker.

  1. […] we could use that as a reference for that person. This reference symbol could be passed as a marker to another context (from β to Ε, say) where it could be interpreted only partially as a […]
