Abstract
========

This 29-page technical report (**EDI-INF-RR-1334**, School of Informatics,
University of Edinburgh, 24 July 2009) provides the extended version of the
EPTCS conference paper on quantifying SBGN-PD diagrams with Bio-PEPA.

The report defines **SBGNtext** --- a textual representation for **SBGN-PD**
(Systems Biology Graphical Notation --- Process Diagrams) --- and implements
the **SBGNtext2BioPEPA** translation tool that automatically converts
SBGNtext descriptions into **Bio-PEPA process algebra** specifications.
The approach is applied to the **MAPK signaling cascade**, demonstrating
both **deterministic** (ODE-based) and **stochastic** (Gillespie-based)
simulations of the pathway.

The report includes full specification details, grammar definitions, and
implementation notes that were necessarily abbreviated in the 15-page
conference publication, making it the definitive reference for anyone
seeking to reproduce or extend the SBGNtext2BioPEPA approach.


Broader Significance (Claude's Assessment)
============================================

This technical report complements the EPTCS paper in important ways:

1. **Complete specification.** Where the conference paper summarized the
   approach, this report provides the full SBGNtext grammar, translation
   rules, and implementation details needed for reproducibility. This
   level of detail is essential for any attempt to extend or reimplement
   the tool.

2. **Formal methods depth.** The report reveals the full depth of formal
   methods work behind the biological application --- defining a textual
   representation language, specifying its grammar, and implementing a
   compiler-like translation pipeline. This pattern (rigorous formal
   specification of biological modeling languages) directly prefigures
   the Evolvix design philosophy.

3. **Deterministic and stochastic analysis.** The report demonstrates
   both ODE-based and stochastic simulation from a single model
   specification, illustrating the power of the process algebra approach
   where the same formal model supports multiple analysis methods.

4. **Edinburgh technical report tradition.** Published as a numbered
   Edinburgh Informatics technical report, this places the work in the
   broader context of the Edinburgh formal methods group's contributions
   to computational biology.
