Sparx EA Consulting
Repository setup, metamodel governance, and enterprise enablement for Sparx Enterprise Architect.
Sparx Enterprise Architect is one of the most capable modeling tools on the market. Most organisations use 20% of what it can do. NILUS helps you close that gap — through proper repository architecture, governance design, and automation that makes EA sustainable at scale.
We work with architecture teams that have outgrown their current Sparx EA setup — single-file repositories, no governance, slow performance — and need a senior practitioner to design a solid foundation.
What We Deliver
Repository Migration
Moving from .eap files or Access to SQL Server, PostgreSQL, or MySQL. We handle schema preparation, data migration, Pro Cloud Server configuration, and post-migration validation.
Metamodel & MDG Design
Custom metamodels, stereotypes, and MDG Technologies aligned to your organisation's architecture language — whether standard or proprietary.
Multi-Team Governance
Package locking, role-based security, baseline management, and collaboration workflows for distributed architecture teams working in a shared repository.
Automation & Scripting
jScript and jArchi-based automation for model validation, report generation, diagram updates, and integration with external systems via the EA API.
Documentation Automation
RTF and HTML template design, structured document generation pipelines, and Prolaborate publishing setup for stakeholder-facing architecture portals.
Pro Cloud Server & Web Access
Full Pro Cloud Server deployment — OSLC, WebEA, Prolaborate, and integration bridge configuration for DevOps and ALM toolchain connectivity.
Common Situations We Resolve
- Repository performance degrading as the model grows past a few thousand elements
- No governance — different teams modeling the same concepts differently
- Locked into .eap files with no concurrent access or version control
- MDG Technologies built years ago that no longer reflect current standards
- Document generation that requires manual cleanup every time
- Pro Cloud Server installed but WebEA or OSLC not properly configured
- Scripting knowledge concentrated in one person who has left
Our Consulting Approach
We start with a structured repository assessment — understanding your current state, governance gaps, and team workflows. From there we design a target architecture and implement changes incrementally, with knowledge transfer built in so your team can sustain the practice independently.
Engagements range from focused one-week interventions (repository migration, MDG design) to multi-month governance and automation programmes alongside your architecture team.
Technologies & Tools
Architecture Publisher
One question comes up on nearly every Sparx engagement: how do the people without a modelling licence read the repository? We built Architecture Publisher to answer it — it generates a branded, searchable static portal from your EA repository and republishes it on a schedule.
