**1. Metadata extraction – new entities & core relationships**

```cheimarr
@date_1855:date {}
@date_1858:date {}
@date_1855_1858:date {start: @date_1855, end: @date_1858}

@faculty_meeting_collection:document {
  title: "Faculty Meeting Minutes, 1855‑1858",
  created: @date_1855_1858,
  language: "en",
  description: "A collection of faculty meeting minutes from the Female Medical College of Pennsylvania covering the years 1855‑1858."
}

@file_pinax -> documents -> @faculty_meeting_collection:document
```

**2. Creators (persons & organizations) – linking to already‑defined entities**

```cheimarr
@faculty_meeting_collection:document -> created_by -> [
  @ellwood_harvey,      # “Ellwood Harvey, Dean”
  @ann_preston,         # “Ann Preston”
  @edwin_fussell,       # “Dr. Fussell” / “Fussell”
  @mark_g_kerr,         # “Kerr”
  @kersey_g_thomas,     # “Thomas”
  @dr_gillingham,       # “Gillingham”
  @dr_russell,          # “Russell”
  @sylvester_birdsell,  # “Birdwell” (assumed same)
  @female_medical_college_of_pennsylvania,
  @t_furrell,
  @edwin_finsell,
  @e_f_russell,
  @edwin_furness,
  @g_finselle
]
```

**3. Subject concepts – reference (common‑knowledge) or create where needed**

```cheimarr
@faculty_meetings:concept {}
@medical_education:concept {}
@committee_appointments:concept {}
@lectures:concept {}
@beneficiaries:concept {}
@advertising:concept {}
@financial_transactions:concept {}
@resignations:concept {}
@women_medical_colleges:concept {}
@preston_retreat:concept {}
@medical_diplomas:concept {}
@anatomy_demonstration:concept {}
@medical_regulations:concept {}
@university_governance:concept {}
@academic_appointments:concept {}
@medical_school_administration:concept {}
@thesis_examination:concept {}
@elections:concept {}

@faculty_meeting_collection:document -> subjects -> [
  @faculty_meetings,
  @medical_education,
  @committee_appointments,
  @lectures,
  @beneficiaries,
  @advertising,
  @financial_transactions,
  @resignations,
  @women_medical_colleges,
  @preston_retreat,
  @medical_diplomas,
  @anatomy_demonstration,
  @medical_regulations,
  @university_governance,
  @academic_appointments,
  @medical_school_administration,
  @thesis_examination,
  @elections
]
```

**4. Places mentioned in the PINAX metadata – new place entities where absent**

```cheimarr
@bucks_county_pa:place {state: @pennsylvania, country: @united_states}
@acton_me:place {state: @maine, country: @united_states}
@utica_ny:place {state: @new_york, country: @united_states}

@faculty_meeting_collection:document -> places -> [
  @philadelphia,
  @n_glastenbury_conn,
  @jamestown_ny,
  @palmyra_ny,
  @toyicroft_md,
  @chester_pa,
  @bucks_county_pa,
  @acton_me,
  @utica_ny
]
```

**5. Synthesis – linking the collection to the individual meeting events across sub‑directories**

```cheimarr
@faculty_meeting_collection:document -> includes_event -> [
  @meeting_1855_04_24:event,
  @meeting_1855_10_05:event,
  @meeting_1855_11_19:event,
  @meeting_1855_12_17:event,
  @meeting_1855_12_31:event,
  @meeting_1856_01_17:event,
  @meeting_1856_01_18:event,
  @meeting_1856_02_28:event,
  @meeting_1856_03_26:event,
  @meeting_1856_04_28:event,
  @meeting_1856_05_28:event,
  @meeting_feb_6_1857:event,
  @meeting_feb_19_1857:event,
  @meeting_feb_23_1857:event,
  @meeting_apr_24_1857:event,
  @meeting_sep_22_1857:event,
  @meeting_sep_25_1857:event,
  @meeting_oct_1857:event,
  @faculty_meeting_february_1858:event
]
```

**6. Cross‑source patterns & recurring entities (synthetic abstraction)**  

*Recurring committees & bodies*  

```cheimarr
@committee_hall:organization -> recurring_in -> [
  @meeting_1855_11_19:event,
  @meeting_1856_01_17:event,
  @meeting_feb_6_1857:event
]

@committee_museum:organization -> recurring_in -> [
  @meeting_1855_11_19:event,
  @meeting_1856_01_17:event,
  @meeting_feb_6_1857:event
]

@beneficiaries_committee:organization -> recurring_in -> [
  @meeting_1855_04_24:event,
  @meeting_1855_10_05:event
]

@board_of_corporators:organization -> recurring_in -> [
  @meeting_1855_12_17:event,
  @meeting_1856_01_17:event,
  @meeting_1856_02_28:event,

```

*Recurring thematic threads*  

```cheimarr
@faculty_meeting_collection:document -> thematic_thread -> [
  {theme: "Facility management", events: [@meeting_1855_11_19:event, @meeting_1855_12_03:event, @meeting_1855_12_17:event]},
  {theme: "Curriculum scheduling", events: [@meeting_1855_10_05:event, @meeting_1856_01_18:event, @meeting_1856_04_28:event, @meeting_feb_6_1857:event]},

**7. Higher‑level abstraction – the series as a concept**

```cheimarr
@faculty_meeting_series:concept {title: "Female Medical College of Pennsylvania Faculty Meeting Series (1855‑1858)"}
@faculty_meeting_series:concept -> comprised_of -> @faculty_meeting_collection:document
@faculty_meeting_series:concept -> spanned_by -> [@date_1855, @date_1858]
@faculty_meeting_series:concept -> involved_person -> [
  @ellwood_harvey,
  @ann_preston,
  @edwin_fussell,
  @mark_g_kerr,
  @kersey_g_thomas,
  @dr_gillingham,
  @dr_russell,
  @sylvester_birdsell,
  @t_furrell,
  @edwin_finsell,
  @e_f_russell,
  @edwin_furness,
  @g_finselle
]
```

*The graph above captures the metadata of the PINAX collection, ties every creator, subject, and place to the existing entities from the 1855‑1858 faculty‑meeting sub‑directories, and synthesises cross‑source patterns such as recurring committees, key personnel, and thematic threads that run through the entire series.*
