1. Introduction: The Disambiguation Problem

The term "Rex Fraction" has established meanings across multiple scientific and legal domains. Rather than competing with these existing uses, this document:

Acknowledges each existing domain and its terminology
Contributes novel terminological infrastructure to each field
Introduces Rex Fraction (Semantic Infrastructure Consulting) as a distinct new entrant
Demonstrates the family resemblances that make the name resonant
Provides clear differentiation through documentation and domain specificity

This approach treats disambiguation as an opportunity for terminological generosity—giving to adjacent fields while staking new ground.

2. Existing Domain: Metallurgy (Recrystallized Fraction)

2.1 Current Terminology

In materials science and metallurgy, the ReX fraction (recrystallized fraction) is a quantitative measurement of material transformation:

Definition: The area or volume percentage of a metal or mineral sample consisting of new, strain-free grains formed after deformation
Measurement: Typically via EBSD (Electron Backscatter Diffraction) mapping
Key metric: GOS (Grain Orientation Spread), often threshold <1.5°
Significance: Indicates how much of a material has undergone structural renewal under pressure

2.2 Terminological Contributions

The following terms are offered to the metallurgical community as potential additions to the analytical vocabulary:

Term	Definition	Application
Grain Orientation Sovereignty	The degree to which a recrystallized grain maintains independent crystallographic identity distinct from its parent structure	Analyzing texture inheritance in recrystallization
Deformation Memory Index (DMI)	A quantitative measure of residual strain information preserved in partially recrystallized microstructures	Tracking processing history through microstructure
Recrystallization Provenance Mapping	Technique for tracing which original (deformed) grains contributed to the formation of specific recrystallized grains	Understanding nucleation site selection
Strain-Free Attribution Protocol	Method for identifying source deformation events from the characteristics of recrystallized microstructure	Forensic metallurgy, failure analysis
Crystallographic Usufruct	The inherited orientation properties that new grains draw from parent structures without full replication	Describing partial texture inheritance
Microstructural Liquidation	The loss of deformation-encoded information during complete recrystallization	Complements existing "recovery" terminology

2.3 Resonance with Semantic Infrastructure

The metallurgical Rex Fraction describes transformation under pressure into strain-free structure. This resonates with semantic infrastructure work:

Deformation → the pressure of extraction and processing
Recrystallization → the formation of new, coherent meaning structures
Strain-free grains → terminology that has achieved stable definition
Provenance mapping → attribution of conceptual origins

The metallurgical and semantic uses share a deep structural metaphor: what emerges coherent from pressure, and how do we trace its origins?

3. Existing Domain: Mining Claims (Geographic/Legal)

3.1 Current Terminology

"Rex Fraction" appears in mining and land records:

Rex Fraction, Idaho: A small area near Murray, Idaho, associated with historical mining
BLM Claims: Formal mining claims documented in Arizona, British Columbia, and other jurisdictions
Legal status: "Fraction" in mining law refers to irregular parcels of land between established claims

3.2 Terminological Contributions

The following terms are offered to mining law and resource geography scholarship:

Term	Definition	Application
Semantic Claim Staking	The act of establishing terminological territory in previously unoccupied conceptual space	Intellectual property theory, terminology governance
Fractional Title Sovereignty	Partial or bounded ownership rights over subdivided territory (physical or conceptual)	Analyzing shared resource rights
Provenance Chain of Title	Documentation linking current claims to original discovery, creation, or registration	Ensuring clear ownership lineage
Terminological Assay	Method for determining the consistency, "purity," or stability of a term's usage across contexts	Language standardization, technical writing
Claim Boundary Disambiguation	The process of clearly marking where one territorial claim ends and another begins	Resolving overlapping usage
Staked Ground Protocol	Formal procedure for registering new terminological territory	Terminology governance frameworks

3.3 Resonance with Semantic Infrastructure

Mining claims establish bounded territory with documented ownership. This resonates with semantic infrastructure work:

Claim staking → establishing terminological authority
Fractional parcels → bounded scope of authorized use (usufruct)
Chain of title → provenance documentation
Boundary disputes → disambiguation work

Both domains address: how do we establish, document, and maintain legitimate claims over territory?

4. Existing Domain: Biochemistry (Bio-Rex Fractionation)

4.1 Current Terminology

In biochemistry, "Rex fraction" appears in the context of ion-exchange chromatography:

Bio-Rex resins: Ion-exchange materials used for separating biological molecules
Fractionation: The process of separating a mixture into distinct components
Elution: The process of extracting adsorbed material from the resin
Application: Toxin purification, protein separation, analytical chemistry

4.2 Terminological Contributions

The following terms are offered to biochemistry and separation science:

Term	Definition	Application
Semantic Elution Gradient	The process by which meaning separates into distinct fractions under analytical pressure	Discourse analysis, content categorization
Meaning Fraction Purity	Measure of how much contextual contamination remains in extracted semantic content	Evaluating summarization quality
Resin-Bound Attribution	Information that remains attached to its source during separation processes	Tracking provenance through processing
Contextual Co-Elution	When related meanings are extracted together, preserving their relationship	Analyzing semantic clustering
Separation Fidelity Index	Measure of how well a fractionation process preserves the integrity of separated components	Quality control for content extraction
Affinity-Based Retrieval	Extraction method that selects content based on structural compatibility rather than simple matching	Improving semantic search

4.3 Resonance with Semantic Infrastructure

Biochemical fractionation involves separating mixtures while tracking what belongs to what. This resonates with semantic infrastructure work:

Fractionation → how meaning gets separated from context
Elution → extraction of content from its original matrix
Purity → whether extracted content retains its integrity
Attribution → knowing which source contributed which fraction

Both domains address: how do we separate, extract, and identify components while maintaining knowledge of their origins?

5. Existing Domain: Paleoceanography (Ethmodiscus rex)

5.1 Current Terminology

In paleoceanography, "rex fraction" refers to measurements involving the giant marine diatom Ethmodiscus rex:

Ethmodiscus rex: A large diatom species used as a proxy for past ocean conditions
Rex fraction: The proportion of E. rex in sediment samples
Application: Reconstructing historical CO2 levels and ocean productivity
Significance: These tiny preserved structures encode information about deep time

5.2 Terminological Contributions

The following terms are offered to paleoceanography and archive science:

Term	Definition	Application
Semantic Sedimentation Rate	The pace at which new meaning accumulates in archival layers (training data, cultural record)	Analyzing how knowledge builds over time
Diatom Archive Principle	The concept that tiny preserved structures can reconstruct large-scale historical conditions	Justifying micro-level analysis for macro understanding
Deep Time Provenance	Attribution that persists across geological or archival timescales	Long-term preservation strategies
Fossilized Semantic Capital	Meaning preserved in archived forms that can be reactivated by later interpreters	Understanding how old texts remain productive
Proxy Signal Fidelity	The degree to which preserved indicators accurately reflect original conditions	Evaluating historical reconstruction methods
Archival Taphonomy	The study of how meaning degrades, transforms, or is preserved through archival processes	Information science, digital preservation

5.3 Resonance with Semantic Infrastructure

Paleoceanographic proxies use preserved micro-structures to reconstruct macro-conditions across deep time. This resonates with semantic infrastructure work:

Diatom preservation → how meaning persists in archives
Sediment cores → the training layer as a record of accumulated meaning
Proxy reconstruction → using artifacts to understand systems
Deep time → the long-term stakes of what gets preserved or lost

Both domains address: how do small preserved structures encode information about large-scale conditions, and how do we read them accurately?
