# Worked example: a web presence on the WEMI spine. A WebSite and
# its WebPages are concrete gmeow:Manifestations — so each embodies an Expression
# that realizes a Work, the same four-tier backing every published artifact
# carries. Pages belong to the site via gmeow:pageOfSite (⊑ partOf). The about
# page names a person as its gmeow:pagePrincipalSubject (⊑ isAbout), which makes
# it a gmeow:ProfilePage by INFERENCE — ProfilePage is a defined class (any
# WebPage whose principal subject is an Agent), so no manual typing is needed.

Guide
Documents — works, releases, segments, and the depiction spine
Slice:
https://blackcatinformatics.ca/gmeow/slices/documents· tier: core The everyday creative-work vocabulary: what got written, released, segmented, titled, and pictured.
Creative works and document metadata — articles, patents, datasets, media, web pages (the schema.org / BIBO / BIBFRAME superset layer).
This slice furnishes the working subkinds of the four-tier WEMI spine:
gmeow:Document, gmeow:Article, gmeow:Patent, gmeow:Dataset,
gmeow:LiteraryWork, gmeow:SerialWork, gmeow:Collection, and gmeow:Service
specialize gmeow:Work (the abstract creation); gmeow:MediaObject, gmeow:WebPage,
gmeow:BookRelease, and gmeow:SerialInstallment specialize gmeow:Manifestation
(the concrete artifact). The umbrella gmeow:CreativeWork is a Category, not a Kind —
identity criteria live on the tiers, never on the umbrella.
Aboutness is kept honest by the tags-slice trichotomy (Principle 9): rdf:type says
what a thing is, gmeow:hasTag says what someone labelled it, and gmeow:isAbout
says what it concerns — three axes, property-disjoint, never collapsed.
gmeow:depicts is the image-shaped arm of isAbout, and gmeow:ContentSegment gives
every work structural decomposition without inventing per-genre part classes. Reading
order, finally, is a standpoint (gmeow:ReadingOrder) — publication order and
internal chronology coexist as subjective orderings, never canonical truth.
Works and their structure
gmeow:CreativeWork
The abstract umbrella Category for intellectual and artistic creations across the WEMI
spine. Formerly a flat Kind (pre WEMI spine); now a Category so each of the four tiers
beneath it can be a gufo:Kind with its own identity criteria. Carries the flat
metadata properties (gmeow:title, gmeow:identifier, gmeow:datePublished, the DC
date and description refinements).
gmeow:ContentSegment
A structural part of a work, release, or installment — chapter, section, scene, episode — a genuine Kind whose identity is position-and-type within a containing whole. One class for all segments: the kind of segment is a value, never a subclass.
gmeow:hasSegment · gmeow:segmentOf
The segment mereology, specializing the universal gmeow:hasPart/gmeow:partOf
spine. segmentOf is transitive — a scene of a chapter of a book is a segment of the
book; hasSegment is its non-functional inverse.
gmeow:segmentType · gmeow:segmentIndex
Per-segment classification and position: segmentType points (functionally) into the
open gmeow:ContentSegmentType value vocabulary (chapter, section, scene, paragraph,
front matter, back matter — seeds, not a closed enum, Principle 9); segmentIndex is a
1-based-by-convention integer.
gmeow:CreativeWorkTitle · gmeow:hasTitle
The structured title: an Appellation subkind carrying its own gmeow:nameLanguage and
gmeow:nameScript, so co-equal multilingual titles ("The Matrix" / "黑客帝国") are
separate first-class objects — never alternateName subordinates, none primary
(Principle 9). Superseded titles set gmeow:displayable false instead of being deleted
(Principle 10). The flat gmeow:title literal remains the 80 %-case shortcut.
gmeow:ReadingOrder
A gmeow:Standpoint subkind that supplies a subjective consumption ordering for the
segments of a work — publication order, internal chronology, author-recommended,
fandom. Claims are annotated gmeow:accordingTo a ReadingOrder; no order is ever
ontology truth.
Syndicated content
gmeow:FeedPosting · gmeow:feedPostingKind · gmeow:quotesContent · gmeow:sharesContent · gmeow:DataFeed
The syndication surface (MoveAction projection). A gmeow:FeedPosting is a short-form work published
to a feed or platform — its kind (gmeow:feedPostingKind: social / blog / microblog)
is an open value, never a subclass (P9), and drives the schema split
(schema:SocialMediaPosting vs schema:BlogPosting). gmeow:quotesContent (with the
inline gmeow:quotedText) becomes schema:Quotation + schema:citation;
gmeow:sharesContent is the repost/boost edge → schema:sharedContent /
sioc:links_to. A gmeow:DataFeed is a published ordered item stream (RSS/Atom/JSON
Feed, a timeline) whose members ride the hasPart spine → schema:DataFeed /
dataFeedElement / DataFeedItem. FeedPostings resolve the email slice's declared
SIOC partiality: a posting IS a sioc:Post, so email is no longer SIOC's only
consumer. (gmeow:Posting in the finance slice is an unrelated ledger term — the feed
posting is deliberately FeedPosting.)
Web presence
gmeow:WebSite · gmeow:pageOfSite · gmeow:pagePrincipalSubject · gmeow:ProfilePage
The web-presence model. A gmeow:WebSite is the published collection; a
gmeow:WebPage belongs to it via gmeow:pageOfSite (a subproperty of partOf, so
site membership rides the universal mereology — the discrete hierarchy a breadcrumb
trail walks). gmeow:pagePrincipalSubject (functional, a subproperty of isAbout) names
the one entity a page principally represents. gmeow:ProfilePage is a defined
class — any WebPage whose pagePrincipalSubject is a gmeow:Agent — so
schema:ProfilePage / schema:WebSite / schema:mainEntityOfPage and the
BreadcrumbList/ListItem walk all derive structurally, never from stored
navigation config.
gmeow:contentLanguage
The natural language of a work's body — distinct from the names slice's
per-appellation language tag, which is the language of a name. Non-functional (a
multilingual work has several); projects to schema:inLanguage / schema:iso6391Code
by reconstructing the BCP-47 / ISO 639-1 code from the gmeow:Language.
Manifestations and the image-depiction spine
gmeow:MediaObject
An image, audio, or video file — a concrete Manifestation carrying the technical
metadata of the design: gmeow:pixelWidth/gmeow:pixelHeight (functional),
gmeow:imageOrientation (EXIF degrees — the transform math is solver work,
Principle 12), gmeow:captureTime (non-functional: EXIF and catalogue claims coexist
with confidence), and gmeow:captureDevice. Declares [gmeow:requiresFrame](../reference/properties/gmeow-requiresFrame.md)
[gmeow:colourspace](../reference/properties/gmeow-colourspace.md) at warning severity (Principle 11).
gmeow:depicts · gmeow:depictedIn
The flat depiction foundation (gathered here by the dependency refactor): any
MediaObject can depict any Entity with zero image machinery, as a subproperty of
gmeow:isAbout. The pair gmeow:pairsWith the gmeow:DepictionUsage relator in the
images extension — promote when context, audience, period, confidence, or evidence of
the depiction matters (regions and scene graphs live there too).
gmeow:colourspace
The colourspace reference frame of a media object's pixel values — sRGB, Adobe RGB,
CMYK — a subproperty of gmeow:hasReferenceFrame (Principle 11: a pixel value is
meaningless without its frame). Deliberately not OWL-functional so merged standpoints
never trigger owl:sameAs collapse; single-valuedness is SHACL's job.
gmeow:BookRelease · gmeow:SerialInstallment
Concrete publication artifacts: an edition or release of a book, and a single issue,
episode, or chapter of a serial. Both are out-of-universe, rights-bearing
Manifestations, held strictly apart from any in-universe narrative frame they source
(linked via gmeow:sourceFor).
Solver layer & alignment
Pixel-space computation — orientation transforms, colourspace conversion, derived thumbnails — belongs to the solver layer (Principle 12); the slice records the claims and their frames. The slice supersets schema.org, BIBO, and BIBFRAME by reference (Principle 5): aligned to, never imported.
Dependencies
Depends on kernel, creative-works (the WEMI spine), names (Appellation),
observations, places, standpoint (ReadingOrder), and tags (the isAbout
trichotomy). Consumed by creative-works manifestations, the mail-corpus attachments,
and depictions of any entity.
