🌐 Open Knowledge License: ODbL + DBCL

TaxisBase is made available under the Open Database License (ODbL): http://opendatacommons.org/licenses/odbl/1.0/. Any rights in individual contents of the database are licensed under the Database Contents License (DBCL): http://opendatacommons.org/licenses/dbcl/1.0/

ODbL + DBCL covers TaxisBase as a database and structured knowledge collection.

TaxisBase is an open collaborative knowledge base containing a core system bootstrap ontology, extensible type system, semantic relationships, constraints, domain/range definitions, and asserted atomic facts for entity types and instances.

TaxisBase defines the canonical knowledge model used by TaxisDB, including the TBox/ABox structure, multidimensional data organization, indexing model, temporal semantics, and database structures.

TaxisDB is the implementation engine; TaxisBase is the database model and knowledge content.

Use, extend, and share TaxisBase freely. Keep the knowledge base open.

ODbL + DBCL Information

✅ You CAN:

  • 🧪 Use TaxisBase for evaluation, research, prototyping, and production
  • 🏢 Use TaxisBase internally within your organization
  • 🛠 Modify the ontology, schema, and knowledge model
  • ➕ Add new entity types, attributes, constraints, and relationships
  • 📚 Populate TaxisBase with your own entities and asserted facts (datoms)
  • 📦 Redistribute TaxisBase and adapted versions under ODbL terms
  • 💼 Use TaxisBase commercially in accordance with ODbL and DBCL

📜 ODbL Covers

The database as a whole, including its organization and knowledge model:

  • 🧩 Bootstrap ontology
  • 🏛 TBox (entity types, attributes, ontology definitions)
  • 📖 ABox (assertion model)
  • 🗂 Database organization on multi-dimensional sparse associative arrays
  • 🔎 Primary and secondary index structures
  • 🔄 Transaction-aware organization
  • 🕒 Temporal and historical semantics
  • 🏗 Supporting database structures (e.g. logger, keywords)

📜 DBCL Covers

The individual contents stored within TaxisBase, including:

  • 🧬 Bootstrap metadata
  • 🏷 Core system vocabulary
  • 🧱 Atomic and composite value types
  • 📑 Enumerated value types and values
  • 🔑 System attributes
  • 🏛 Abstract types
  • 📘 Entity type definitions
  • 🔗 Relationships and constraints
  • 📐 Domain and range definitions
  • 📄 Entity instances
  • ⚛ Asserted atomic facts (datoms)
  • 🤝 Community-contributed knowledge

🔄 Share-Alike

If you publicly distribute an adapted TaxisBase database, you must comply with the ODbL Share-Alike requirements.

This means adapted versions of TaxisBase must remain available under ODbL, together with the required attribution and licensing notices.

❌ ODbL + DBCL DO NOT Cover

These licenses do not apply to software components, including:

  • ⚙️ TaxisDB database engine
  • 💾 YottaDB storage engine

Software licensing is separate:

TaxisDB Engine  → SSPLv1
YottaDB Engine   → GNU AGPL v3.0

™ Trademarks

ODbL and DBCL do not grant rights to use:

  • TaxisDB name
  • TaxisBase name
  • Official logos
  • Project branding

Trademark rights remain with the project owner.

Proprietary extensions

ODbL/DBCL do not grant:

  • Ownership of TaxisBase
  • Rights to claim official TaxisBase status
  • Rights to use Taxis trademarks
  • Commercial endorsement

🧭 Quick Decision Guide

IF you use TaxisBase internally
→ No publication required

IF you extend the ontology
→ You may keep modifications private unless you publicly distribute
   the adapted database

IF you add new types, attributes, entities or facts
→ They become part of your adapted TaxisBase database

IF you publicly distribute an adapted TaxisBase database
→ ODbL Share-Alike obligations apply

IF you redistribute TaxisBase contents
→ DBCL applies to the individual contents

IF you use TaxisDB software
→ SSPLv1 applies to the engine
