**Person**: Human entities and individuals + * - **Organization**: Formal organizations, companies, institutions + * - **Location**: Geographic locations, places, addresses + * - **Thing**: Physical objects and tangible items + * - **Concept**: Abstract ideas, concepts, and intangible entities + * - **Event**: Occurrences with time and place dimensions + * + * ### Digital/Content Types + * - **Document**: Text-based files and documents + * - **Media**: Non-text media files (images, videos, audio) + * - **File**: Generic digital files + * - **Message**: Communication content + * - **Content**: Generic content that doesn't fit other categories + * + * ### Collection Types + * - **Collection**: Generic groupings of items + * - **Dataset**: Structured collections of data + * + *

and workflow items + * - **Project**: Organized initiatives with goals and timelines + * + * ### Descriptive Types + * - **Process**: Workflows, procedures, and sequences + * - **State**: States, conditions, or statuses + * - **Role**: Roles, positions, or responsibilities + * - **Topic**: Subjects or themes + * - **Language**: Languages or linguistic entities + * - **Currency**: Currencies and monetary units + * - **Measurement**: Measurements, metrics, or quantities + * + * ## Verb Types (Relationships) + * + * Verb types represent relationships between entities and are organized into categories: + * + * ### Core Relationship Types + * - **RelatedTo**: Generic relationship (default fallback) + * - **Contains**: Containment relationship + * - **PartOf**: Part-whole relationship + *

Modeling Different Graph Types + * + * This type system can model various graph structures: + * + * ### Knowledge Graphs + * Use Person, Organization, Location, Concept entities with semantic relationships + * like AttributedTo, LocatedAt, RelatedTo + * + * ### Social Networks + * Use Person, User entities with social relationships like FriendOf, Follows, + * WorksWith, Communicates + * + * ### Content Networks + * Use Document, Media, Content entities with relationships like References, + * CreatedBy, Contains, Categorizes + * + * ### Business Process Models + * Use Task, Process, Role entities with relationships like Precedes, Requires, + * DependsOn, Transforms + * + * ### Organizational Charts + * Use Person, Role, Organization entities with relationships like ReportsTo, + * Supervises, MemberOf + * + * The flexibility of this system allows it to represent any domain while + * maintaining semantic consistency and enabling powerful graph operations + * and reasoning

into categories: + * + * ### Core Entity Types + * - **Person**: Human entities and individuals + * - **Organization**: Formal organizations, companies, institutions + * - **Location**: Geographic locations, places, addresses + * - **Thing**: Physical objects and tangible items + * - **Concept**: Abstract ideas, concepts, and intangible entities + * - **Event**: Occurrences with time and place dimensions + * + * ### Digital/Content Types + * - **Document**: Text-based files and documents + * - **Media**: Non-text media files (images, videos, audio) + * - **File**: Generic digital files + * - **Message**: Communication content + * - **Content**: Generic content that doesn't fit other categories + * + * ### Collection Types + * - **Collection**: Generic groupings of items + * - **Dataset**: Structured collections of data + * + * ### Business/Application Types + * - **Product**: Commercial products and offerings + * - **Service**: Services and offerings + * - **User**: User accounts and profiles + * - **Task**: Actions, todos, and workflow items + * - **Project**: Organized initiatives with goals and timelines + * + * ### Descriptive Types + * - **Process**: Workflows, procedures, and sequences + * - **State**: States, conditions, or statuses + * - **Role**: Roles, positions, or responsibilities + * - **Topic**: Subjects or themes + * - **Language**: Languages or linguistic entities + * - **Currency**: Currencies and monetary units + * - **Measurement**: Measurements, metrics, or quantities + * + * ## Verb Types (Relationships) + * + * Verb types represent relationships between entities and are organized into categories: + * + * ### Core Relationship Types + * - **RelatedTo**: Generic relationship (default fallback) + * - **Contains**: Containment relationship + * - **PartOf**: Part-whole relationship + * - **LocatedAt**: Spatial relationship + * - **References**: Reference or citation relationship + * + * ### Temporal/Causal Types + * - **Precedes/Succeeds**: Temporal sequence relationships + * - **Causes**: Causal relationships + * - **DependsOn**: Dependency relationships + * - **Requires**: Necessity relationships + * + * ### Creation/Transformation Types + * - **Creates**: Creation relationships + * - **Transforms**: Transformation relationships + * - **Becomes**: State change relationships + * - **Modifies**: Modification relationships + * - **Consumes**: Consumption relationships + * + * ### Ownership/Attribution Types + * - **Owns**: Ownership relationships + * - **AttributedTo**: Attribution or authorship + * - **CreatedBy**: Creation attribution + * - **BelongsTo**: Belonging relationships + * + * ### Social/Organizational Types + * - **MemberOf**: Membership or affiliation + * - **WorksWith**: Professional relationships + * - **FriendOf**: Friendship relationships + * - **Follows**: Following relationships + * - **Likes**: Liking relationships + * - **ReportsTo**: Reporting relationships + * - **Supervises**: Supervisory relationships + * - **Mentors**: Mentorship relationships + * - **Communicates**: Communication relationships + * + * ### Descriptive/Functional Types + * - **Describes**: Descriptive relationships + * - **Defines**: Definition relationships + * - **Categorizes**: Categorization relationships + * - **Measures**: Measurement relationships + * - **Evaluates**: Evaluation or assessment relationships + * - **Uses**: Utilization relationships + * - **Implements**: Implementation relationships + * - **Extends**: Extension relationships + * + * ## Usage with Additional Metadata + * + * While the type system provides a standardized vocabulary, additional metadata + * can be attached to any entity or relationship to capture domain-specific + * information: + * + * ```typescript + * const person: GraphNoun = { + * id: 'person-123', + * noun: NounType.Person, + * data: { + * name: 'John Doe', + * age: 30, + * profession: 'Engineer' + * } + * } + * + * const worksFor: GraphVerb = { + * id: 'verb-456', + * source: 'person-123', + * target: 'org-789', + * verb: VerbType.MemberOf, + * data: { + * role: 'Senior Engineer', + * startDate: '2020-01-01', + * department: 'Engineering' + * } + * } + * ``` + * + * ## Modeling Different Graph Types + * + * This type system can model various graph structures: + * + * ### Knowledge Graphs + * Use Person, Organization, Location, Concept entities with semantic relationships + * like AttributedTo, LocatedAt, RelatedTo + * + * ### Social Networks + * Use Person, User entities with social relationships like FriendOf, Follows, + * WorksWith, Communicates + * + * ### Content Networks + * Use Document, Media, Content entities with relationships like References, + * CreatedBy, Contains, Categorizes + * + * ### Business Process Models + * Use Task, Process, Role entities with relationships like Precedes, Requires, + * DependsOn, Transforms + * + * ### Organizational Charts + * Use Person, Role, Organization entities with relationships like ReportsTo, + * Supervises, MemberOf + * + * The flexibility of this system allows it to represent any domain while + * maintaining semantic consistency and enabling powerful graph operations + * and reasoning capabilities. + */ +/** + * Defines valid noun types for graph entities + * Used for categorizing different types of nodes + */

Additional metadata can be attached to any entity or relationship + * - **Semantic**: Types carry meaning that can be used for reasoning and inference + * + * ## Noun Types (Entities) + * + * Noun types represent entities in the graph and are organized into categories: + * + * ### Core Entity Types + * - **Person**: Human entities and individuals + * - **Organization**: Formal organizations, companies, institutions + * - **Location**: Geographic locations, places, addresses + * - **Thing**: Physical objects and tangible items + * - **Concept**: Abstract ideas, concepts, and intangible entities + * - **Event**: Occurrences with time and place dimensions + * + * ### Digital/Content Types + * - **Document**: Text-based files and documents + * - **Media**: Non-text media files (images, videos, audio) + * - **File**: Generic digital files + * - **Message**: Communication content + * - **Content**: Generic content that doesn't fit other categories + * + * ### Collection Types + * - **Collection**: Generic groupings of items + * - **Dataset**: Structured collections of data + * + * ### Business/Application Types + * - **Product**: Commercial products and offerings + * - **Service**: Services and offerings + * - **User**: User accounts and profiles + * - **Task**: Actions, todos, and workflow items + * - **Project**: Organized initiatives with goals and timelines + * + * ### Descriptive Types + * - **Process**: Workflows, procedures, and sequences + * - **State**: States, conditions, or statuses + * - **Role**: Roles, positions, or responsibilities + * - **Topic**: Subjects or themes + * - **Language**: Languages or linguistic entities + * - **Currency**: Currencies and monetary units + * - **Measurement**: Measurements, metrics, or quantities + * + * ## Verb Types (Relationships) + * + * Verb types represent relationships between entities and are organized into categories: + * + * ### Core Relationship Types + * - **RelatedTo**: Generic relationship (default fallback) + * - **Contains**: Containment relationship + * - **PartOf**: Part-whole relationship + * - **LocatedAt**: Spatial relationship + * - **References**: Reference or citation relationship + * + * ### Temporal/Causal Types + * - **Precedes/Succeeds**: Temporal sequence relationships + * - **Causes**: Causal relationships + * - **DependsOn**: Dependency relationships + * - **Requires**: Necessity relationships + * + * ### Creation/Transformation Types + * - **Creates**: Creation relationships + * - **Transforms**: Transformation relationships + * - **Becomes**: State change relationships + * - **Modifies**: Modification relationships + * - **Consumes**: Consumption relationships + * + * ### Ownership/Attribution Types + * - **Owns**: Ownership relationships + * - **AttributedTo**: Attribution or authorship + * - **CreatedBy**: Creation attribution + * - **BelongsTo**: Belonging relationships + * + * ### Social/Organizational Types + * - **MemberOf**: Membership or affiliation + * - **WorksWith**: Professional relationships + * - **FriendOf**: Friendship relationships + * - **Follows**: Following relationships + * - **Likes**: Liking relationships + * - **ReportsTo**: Reporting relationships + * - **Supervises**: Supervisory relationships + * - **Mentors**: Mentorship relationships + * - **Communicates**: Communication relationships + * + * ### Descriptive/Functional Types + * - **Describes**: Descriptive relationships + * - **Defines**: Definition relationships + * - **Categorizes**: Categorization relationships + * - **Measures**: Measurement relationships + * - **Evaluates**: Evaluation or assessment relationships + * - **Uses**: Utilization relationships + * - **Implements**: Implementation relationships + * - **Extends**: Extension relationships + * + * ## Usage with Additional Metadata + * + * While the type system provides a standardized vocabulary, additional metadata + * can be attached to any entity or relationship to capture domain-specific + * information: + * + * ```typescript + * const person: GraphNoun = { + * id: 'person-123', + * noun: NounType.Person, + * data: { + * name: 'John Doe', + * age: 30, + * profession: 'Engineer' + * } + * } + * + * const worksFor: GraphVerb = { + * id: 'verb-456', + * source: 'person-123', + * target: 'org-789', + * verb: VerbType.MemberOf, + * data: { + * role: 'Senior Engineer', + * startDate: '2020-01-01', + * department: 'Engineering' + * } + * } + * ``` + * + * ## Modeling Different Graph Types + * + * This type system can model various graph structures: + * + * ### Knowledge Graphs + * Use Person, Organization, Location, Concept entities with semantic relationships + * like AttributedTo, LocatedAt, RelatedTo + * + * ### Social Networks + * Use Person, User entities with social relationships like FriendOf, Follows, + * WorksWith, Communicates + * + * ### Content Networks + * Use Document, Media, Content entities with relationships like References, + * CreatedBy, Contains, Categorizes + * + * ### Business Process Models + * Use Task, Process, Role entities with relationships like Precedes, Requires, + * DependsOn, Transforms + * + * ### Organizational Charts + * Use Person, Role, Organization entities with relationships like ReportsTo, + * Supervises, MemberOf + * + * The flexibility of this system allows it to represent any domain while + * maintaining semantic consistency and enabling powerful graph operations + * and reasoning capabilities. + */ + +// Common metadata types +/** + * Represents a high-precision timestamp
