IsoFind Editions
Coming Soon. The multi-edition architecture is currently being implemented. As of the publication of this page, only the IsoFind Pro edition is available for distribution. The IsoFind Lite, GeoFind, SupplyFind, and PetroFind editions are announced here to provide visibility on the roadmap but are not yet available for download. This page will be updated as new releases roll out.
IsoFind covers a wide spectrum of disciplines, from hydrogeochemistry and environmental tracers to petroleum geology and raw material traceability. This breadth creates a challenge: a user working exclusively on hydrocarbons does not need the pesticide CSIA module, and an industrial buyer verifying the origin of a copper batch does not need the 3D simulation engine. To address this diversity without sacrificing software coherence, IsoFind SAS is preparing five distinct editions, built from a single codebase via a system of compilation flags. This page presents the five planned editions, their positioning, and the technical principles behind them.
The Five Planned Editions
The editions are distinguished by their functional scope and target audience. They share the same technical foundation (Tauri + Rust + FastAPI + SQLite), the same ISOF format, the same 3D simulation engine, and the same offline / sovereign architecture. Only the activated business modules change.
| Edition | Target Audience | Scope | Status |
|---|---|---|---|
| IsoFind Pro | Environmental consultancies, reference laboratories | Full suite: inorganic geochemistry, organic CSIA, 3D simulation, signed reports, full API | Distributed |
| IsoFind Lite | Students, occasional academic projects, evaluation | Sample entry and visualization, CSV import, Geochemistry view, simple reports without signatures or CSIA | Upcoming |
| GeoFind | Geologists, lithological mapping, exploration geochemistry | Focus on major and trace elements, lithological ratios, stratigraphic profiles, geochemical maps | Upcoming |
| PetroFind | Petroleum geologists, hydrocarbon geochemists | Focus on PAHs, BTEX, biomarkers, petrogenic vs. pyrogenic ratios, δ¹³C and δ²H signatures | Upcoming |
| SupplyFind | Industrial companies, procurement departments, ESG compliance, due diligence | Supply chain traceability, raw material origin attribution, CBAM compliance, and duty of care | Upcoming |
IsoFind Pro
The reference edition, currently being distributed. It includes all functionalities documented on this site: full molecular catalog (156 molecules, 50 degradation pathways, 56 CSIA fractionations), full inorganic suite (11 elements with epsilons, redox speciation), 3D simulation (ADE engine, Nexus bridge, ML priors), reporting module with ECDSA P-256 signatures for the ISOF format, and exhaustive API. This is the only edition available today; the others are variants built from the same code.
IsoFind Lite
A lightweight edition intended for education, software evaluation, or projects that do not require the advanced engine. It retains sample entry, the Geochemistry view, CSV imports, and simple report exports. It will not include CSIA, 3D simulation, or cryptographic signatures for ISOF reports. Its file format remains ISOF but at Level 0 (unsigned) to allow data exchange between Lite and Pro users.
| Functionality | Pro | Lite |
|---|---|---|
| Sample entry and visualization | Yes | Yes |
| Geochemistry View (Majors & Traces) | Yes | Yes |
| Molecules View (Catalog, Compliance) | Yes | Read-only, no CSIA |
| Vertical profiles, 2D maps | Yes | Yes |
| 3D Simulation | Yes | No |
| CSIA and Nexus Bridge | Yes | No |
| PDF Reports | Full templates + custom blocks | Simple templates only |
| ISOF Signature (ECDSA P-256) | Yes (Level 2) | No (Level 0 only) |
| Full API | Yes | Read-only |
GeoFind
An edition specialized for geologists and exploration geochemists. GeoFind focuses on lithological characterization and the interpretation of natural geochemical signatures rather than contamination forensics. It utilizes the IsoFind core but highlights specific geological business functionalities.
| GeoFind Module | Usage |
|---|---|
| Extended Majors and Traces | REE (Rare Earth Elements) support, integration of 14 lanthanides + Y |
| Europium and other anomalies | Automatic calculation of Eu/Eu*, Ce/Ce*, comparison to UCC / PAAS |
| Lithological Ratios | Ca/Mg, Na/K, Rb/Sr, K/Rb with geological interpretation |
| Classification Diagrams | TAS, AFM, Pearce, ternary diagrams |
| Dating and Geochronology | Isotopic ratios ²⁰⁶/²⁰⁷/²⁰⁸ Pb, ⁸⁷Sr/⁸⁶Sr |
| Enhanced Stratigraphic Profiles | Paleo-environmental constraints, paleo-redox indicators |
| Prospecting Maps | Isoconcentrations, anomalies relative to local background |
The CSIA bridge remains available but is disabled by default in GeoFind. Users who occasionally need CSIA functionality can activate it via settings; this conditional activation logic is one of the advantages of the single-codebase architecture.
PetroFind
An edition dedicated to petroleum geochemists and hydrocarbon cases. PetroFind centers the interface around PAHs, BTEX (currently being added to the main catalog), molecular biomarkers, and δ¹³C and δ²H isotopic signatures specific to hydrocarbons. It is designed for source attribution in petroleum product contamination.
| PetroFind Module | Usage |
|---|---|
| Extended Petroleum Catalog | 16 EPA PAHs + methylated PAHs + biomarkers (steranes, terpanes, hopanes) |
| BTEX and Aliphatic Hydrocarbons | Complete benzene, toluene, ethylbenzene, xylenes family, TPH C10-C40 |
| Petro/Pyro Diagnostic Ratios | 6 classic PAH ratios, multi-ratio combined scoring |
| Petroleum Fingerprinting | Identification via complete molecular signature |
| Hydrocarbon CSIA | δ¹³C and δ²H on BTEX, PAHs, and biomarkers |
| Petroleum Biodegradation | Differential degradation models based on mode (normal paraffin loss, isoprenoid, UCM) |
| Weathering and Evaporation | Modeling the evolution of a petroleum product over time |
SupplyFind
An edition geared toward industrial supply chain traceability. SupplyFind is designed for a non-scientific audience: procurement departments, compliance officers, CSR teams, lawyers specializing in duty of care, and third-party auditors. The interface hides the underlying geochemistry and presents origin attribution results that are directly actionable in a compliance file. It relies on the same isotopic engine as the scientific editions but exposes radically different workflows.
Typical use cases involve materials where provenance determines legal or commercial acceptability: critical metals (cobalt, lithium, tungsten, tantalum), rare earths, wood and fibers, alloys and processed products, conflict minerals, green steel vs. conventional steel. The question asked is not "what happened at this contaminated site?" but "did this batch truly originate from the stated mine?".
| SupplyFind Module | Usage |
|---|---|
| Reference Signature Database | Library of isotopic signatures by mine, deposit, or processing plant |
| Origin Attribution by Matching | Comparison of a measured batch against the database, probability scoring per candidate source |
| Upstream Reconstruction | Tracing signatures back through industrial transformations (smelting, rolling, alloying) |
| CBAM Compliance | Reports aligned with the EU Carbon Border Adjustment Mechanism, geographic origin certificates |
| Duty of Care (Vigilance) | Support for French Law 2017-399 and CSRD / CS3D directives, evidence of reasonable diligence |
| Conflict Minerals | Support for EU Regulation 2017/821 (3TG: tin, tantalum, tungsten, gold) |
| Auditable Reports | ECDSA P-2516 signed PDFs acceptable by third-party auditors, traceable chain of evidence |
| ERP Integration API | Endpoints compatible with procurement information systems (SAP Ariba, Coupa, etc.) |
SupplyFind differs from other editions in its target audience and the nature of its reports. Where IsoFind Pro produces scientific dossiers for experts, SupplyFind produces certificates of compliance intended for integration into corporate document management systems. The vocabulary used in the interface is intentionally de-jargonized: it speaks of origin, batch, supplier, and sampling date rather than δ¹³C, fractionation, and residual fraction.
The scientific rigor remains the same: it is the IsoFind isotopic engine that calculates attribution. However, the compartmentalized interface completely changes the experience. A SupplyFind procurement manager does not need to understand CSIA to utilize an origin result. This approach is essential for distributing the product beyond specialized laboratories.
Technical Principle: One Codebase, Multiple Editions
The five editions are not forks or distinct branches in the repository. They are built from the same source code through a conditional compilation system driven by an editions.toml file. This approach prevents code divergence between editions and ensures that bug fixes benefit all versions simultaneously.
| Principle | Implementation |
|---|---|
| Single Git Repository | No lite branch, no geofind fork |
| editions.toml File | Defines compilation flags per edition |
| Rust Compilation Flags (Tauri side) | #[cfg(feature = "isof_sign")], #[cfg(feature = "csia")], etc. |
| Python / FastAPI Flags | ISOFIND_EDITION=pro environment variables, conditional route loading |
| Assets and Branding | Logo, palette, and product name parameterized by edition |
| Build Output | Distinct Inno Setup installers: IsoFind-Pro-1.x.x.exe, GeoFind-1.x.x.exe, etc. |
This single-codebase architecture is a significant engineering choice. It imposes discipline in code organization (each module must be cleanly toggleable), but it reduces the maintenance load fivefold and guarantees consistency across editions. An IsoFind Pro user and a SupplyFind user work with the same core engine version; only the surface modules differ.
Licensing and Compatibility
The ISOF format remains common to all five editions. An ISOF file generated by IsoFind Pro can be opened for viewing by IsoFind Lite, GeoFind, PetroFind, or SupplyFind, regardless of its origin. Specific functionalities not supported by an edition are displayed as grayed out with an information message rather than preventing the file from opening. This portability is essential for exchange between multidisciplinary teams and is particularly valuable in the SupplyFind case, where a procurement team may receive a scientific report from a Pro laboratory and utilize it in their compliance context.
| Action | Inter-edition Behavior |
|---|---|
| Open a signed ISOF (Level 2) in Lite | Reading OK, signature verification displayed but not actionable |
| Open a Pro ISOF with simulation in GeoFind | Samples and measurements OK, simulation volume grayed out with message |
| Open a PetroFind ISOF with biomarkers in Pro | Full reading, the extended petroleum catalog is dynamically loaded |
| Open a SupplyFind ISOF in Pro | Full reading including industrial reference signatures and certificates of origin |
| Open a Pro ISOF in SupplyFind | Reading of relevant isotopic signatures, environmental CSIA modules grayed out |
| Exporting from a lower edition | Absent modules are not written to the ISOF, preventing corruption |
Indicative Roadmap
The release schedule for the editions will depend on user feedback and development pace. The milestones targeted at this stage are indicative and non-contractual.
| Edition | Milestone | Priority Features |
|---|---|---|
| IsoFind Pro | Distributed | All functionalities documented on this site |
| IsoFind Lite | Short term | Data entry, Geochemistry view, simple reports, ISOF Level 0 |
| PetroFind | Medium term | BTEX integration, biomarkers, automated petro/pyro ratios |
| GeoFind | Medium term | REE + anomalies, classification diagrams, dating |
| SupplyFind | Medium to long term | Industrial signature database, ERP connectors, CBAM / Duty of care report templates |
Link with the IsoFind Ecosystem
The addition of specialized editions does not affect the other pillars of the product. Fundamental technical guarantees remain identical across all editions.
- Offline / Air-gapped Architecture: No edition requires an internet connection to function.
- Data Sovereignty: ISOF files remain on the user's machine; no data is sent to IsoFind SAS.
- Offline ECDSA P-256 Licenses: License validation occurs locally without network calls.
- Common ISOF Format: Guaranteed portability between editions and major versions.
- Python isof Publication on PyPI: ISOF reading and verification available open-source for all users, regardless of edition.
How to Contribute
User feedback on the planned editions is particularly valuable at this pre-publication stage. Feature priorities, observed frustrations, and specific business needs can guide the scope choices for each edition. The usual feedback channels (site contact form, published email addresses, GitHub for technical aspects) remain open.
A use case that does not fit into the five currently planned editions is a strong signal. The single-codebase architecture allows for the relatively easy addition of a sixth or seventh edition, provided user demand is clear and the module separation logic holds. Possibilities such as a Medical edition (tracing trace elements in the pharmaceutical chain) or an Agri-food edition (ingredient origin, label authentication) are regularly discussed.
