Overall Assessment:
★★★★☆ - Specialized technology provider for enterprise integration
GLOMIDCO is a specialized XBRL technology provider focused on enabling
STP (Straight-Through Processing) integration within enterprise systems.
The vision is embedding XBRL capabilities into ERP systems (SAP, Oracle)
and middleware layers for large corporations. Although founded in the
Netherlands, the focus is NOT on the Dutch market but on international
enterprise integration. The 3-stage architecture and Table Linkbase
expertise (COREP/FINREP 60+ tables) make it highly suitable for banking
supervision and insurance regulation. Development paused in 2016, but
the technology remains mature and widely used in production environments.
Ideal for: System integrators building XBRL into ERP/middleware, banks
needing COREP/FINREP processing, large corporations with SAP/Oracle
seeking XBRL integration, enterprises wanting STP from business systems
to regulatory reporting.
NOT ideal for: Small companies needing turnkey solution, organizations
wanting SaaS platform, projects without integration expertise.

└─ Accounting software integration (.NET-based)
Overall Assessment:
★★★★☆ - Advanced .NET processor, excellent for central banks and SBR
Semansys is a technically advanced XBRL processor with strong credentials
in central banking and regulatory reporting. The .NET implementation is
mature and capable, with complete Formula 1.0 support. However, the
straight-through processing (STP) architecture lacks the design/init/runtime
separation found in processors like GLOMIDCO, making it less suitable for
distributed processing scenarios or Java ecosystem integration. Excellent
choice for .NET-based solutions, particularly in European regulatory
reporting (SBR, ESEF, ESG/CSRD) and central bank applications.
For Java-based integration or distributed processing architectures,
GLOMIDCO's 3-stage model (design/init/runtime) is more appropriate.

## Part 6: Processor Architecture Analysis
### 6.1 Design/Init/Runtime vs. Straight-Through Processing (STP)
**Critical Architectural Distinction:**
XBRL processors can be architected in fundamentally different ways, which has major implications for integration, performance, and scalability:
Two Main Architectural Approaches:
Three-Stage Architecture (Design/Init/Runtime)
├─ Stage 1: DESIGN TIME
│ ├─ Taxonomy analysis and parsing
│ ├─ Schema generation (XBRLX, etc.)
│ ├─ Metadata extraction
│ ├─ Validation rule compilation
│ └─ Occurs once, cached
├─ Stage 2: INIT (Initialization)
│ ├─ Load pre-processed taxonomy
│ ├─ Initialize validation engine
│ ├─ Setup context
│ └─ Prepare for runtime
└─ Stage 3: RUNTIME
├─ Process XBRL instances
├─ Validate facts
├─ Execute formulas
├─ Generate output
└─ Optimized for high-volume
Straight-Through Processing (STP)
├─ Single-pass processing
├─ Load taxonomy + process instance together
├─ No separation of stages
├─ Simpler architecture
└─ Less optimal for high-volume
### 6.2 Architectural Comparison Table
Processor Architecture Matrix:
| Processor | Architecture | Design | Init | Runtime | STP | Distributed | Java | .NET | Notes |
|---|---|---|---|---|---|---|---|---|---|
| GLOMIDCO | 3-Stage | ✅ | ✅ | ✅ | ❌ | ✅ | ✅ | ⚠️ | Full 3-stage, distributed table processing |
| Fujitsu XWand | 3-Stage | ✅ | ✅ | ✅ | ❌ | ✅ | ✅ | ❌ | Enterprise-grade, high performance |
| CoreFiling Beacon | Hybrid | ✅ | ⚠️ | ✅ | ⚠️ | ✅ | ✅ | ❌ | Microservices, API-first |

⚠️ Partial support / Can be adapted
❌ Not supported / Not designed for this
### 6.3 Architectural Trade-offs
**3-Stage Architecture (Design/Init/Runtime) Advantages:**
Advantages:
✅ High-volume processing
├─ Design-time work done once
├─ Runtime optimized for speed
├─ Process thousands of instances efficiently
└─ Example: GLOMIDCO processes 60+ COREP tables independently
✅ Distributed processing
├─ Can distribute runtime across nodes
├─ Share pre-processed taxonomy
├─ Parallel processing possible
└─ Example: GLOMIDCO table-by-table processing
✅ Memory efficiency
├─ Don't reload taxonomy for each instance
├─ Smaller runtime memory footprint
├─ Can handle large taxonomies (US GAAP 18K+ concepts)
└─ Critical for embedded systems
✅ Enterprise integration
├─ Separate design-time tools
├─ Init can happen at deployment
├─ Runtime can be embedded
└─ Good for SDK/library model
✅ Caching optimization
├─ Design-time artifacts cached
├─ DTS (Discoverable Taxonomy Set) pre-built
├─ Validation rules compiled
└─ Formula expressions optimized
Disadvantages:
⚠️ More complex architecture
⚠️ Requires state management

⚠️ Reload taxonomy for each instance
⚠️ Higher memory usage
⚠️ Less efficient for distributed processing
⚠️ Not ideal for embedded/SDK scenarios
Best For:
### 6.4 Use Case Recommendations
**When to Choose 3-Stage Architecture:**
Choose GLOMIDCO, Fujitsu XWand, or similar:
Banking Supervision (COREP/FINREP)
├─ 60+ tables to process
├─ Same taxonomy, thousands of instances
├─ Monthly/quarterly submission
└─ Distributed processing beneficial
High-Volume Regulatory Reporting
├─ Thousands of companies
├─ Same taxonomy for all
├─ Batch processing
└─ Performance critical
SDK/Library Integration
├─ Embed in accounting software
├─ Multiple customers using same taxonomy
├─ Memory efficiency critical
└─ Example: Enterprise ERP/middleware integration (SAP, Oracle)
Enterprise On-Premise
├─ Large taxonomy (US GAAP, IFRS)
├─ Multiple divisions reporting
├─ Control over infrastructure
└─ Long-running processes
Java Ecosystem
├─ Java-based enterprise applications
├─ J2EE, Spring, etc.
├─ Standard integration patterns
└─ GLOMIDCO (Java) or Fujitsu XWand (Java)
**When to Choose STP Architecture:**
Choose Workiva, IRIS CARBON, Semansys (.NET), or similar:
Cloud SaaS Deployment
├─ Horizontal scaling
├─ Stateless processing
├─ Container-based
└─ Modern cloud architectures
Low-Volume Processing
├─ Annual reports only
├─ Small number of filings
├─ Performance not critical
└─ Simplicity preferred
.NET Ecosystem
├─ .NET-based applications
├─ Azure cloud deployment
├─ Windows environments
└─ Semansys (.NET) or Altova (.NET)
Quick Start / Prototyping
├─ Fast time to market
├─ Proof of concept
├─ Simple integration
└─ Arelle (Python) for testing
Service Provider Model
├─ Bureau services
├─ Managed services
├─ Customer uploads files
└─ DataTracks, DFIN, Toppan Merrill
### 6.5 Integration Experience: Semansys .NET → Java
**Real-World Integration Challenge:**
Challenge: Wrapping Semansys .NET processor for Java use
Approach: JNI (Java Native Interface)
Result: ⚠️ Architecture mismatch
Technical Issues:
├─ No Design/Init/Runtime separation
│ ├─ STP architecture loads taxonomy every time
│ ├─ Cannot pre-initialize for Java application
│ ├─ Higher overhead for repeated processing
│ └─ Memory pressure in Java environment
├─ JNI Complexity
│ ├─ .NET → Native → JNI bridging
│ ├─ Type marshaling overhead
│ ├─ Garbage collection coordination
│ └─ Debugging difficulties
├─ Platform Dependencies
│ ├─ .NET runtime required
│ ├─ Windows-preferred (Mono possible but complex)
│ ├─ Deployment complications
│ └─ Linux/Unix challenges
└─ Performance Overhead
├─ Cross-language boundary crossing
├─ Serialization/deserialization
├─ Memory copying
└─ No caching benefits
Conclusion:
For Java-based integration with design/init/runtime requirements,
native Java processors (GLOMIDCO, Fujitsu XWand, CoreFiling) are
significantly more suitable than .NET processors wrapped via JNI.
Semansys remains excellent for:
✅ Native .NET integration
✅ Azure cloud deployments
✅ Central bank applications (where .NET is standard)
✅ European regulatory reporting (SBR, ESEF)
