**1. Define the PIN metadata file as a document and capture its core attributes**

@file_pinax:document {title: "Drexel University Historical Records", type: "Collection", institution: @final_drexel_university, created: @date_1861_1863, language: "en", description: "A collection of historical records from Drexel University, including commencement and graduation records, faculty meeting minutes, and miscellaneous documents from the early 1860s.", subjects: ["Commencement","Graduation","Education","Voting","19th Century","Faculty meetings","Resignations","College administration","Medical education","Academic appointments","Medical theses","College organization","Academic administration","College governance","Historical documents"]}

**2. Link creators (persons & organization) to the document**

@a_preston -> creator_of -> @file_pinax  
@e_h_cleveland -> creator_of -> @file_pinax  
@dr_birdsell -> creator_of -> @file_pinax  
@dr_fussell -> creator_of -> @file_pinax  
@dr_temple -> creator_of -> @file_pinax  
@dr_kerr -> creator_of -> @file_pinax  
@dr_booth -> creator_of -> @file_pinax  
@dr_locatis -> creator_of -> @file_pinax  
@dr_russell -> creator_of -> @file_pinax  
@dr_simple -> creator_of -> @file_pinax  
@edwin_fassell -> creator_of -> @file_pinax  
@c_h_j_scarlett -> creator_of -> @file_pinax  
@female_medical_college_of_pennsylvania -> creator_of -> @file_pinax  

**3. Connect the document to its holding institution**

@final_drexel_university -> holds -> @file_pinax  

**4. Create a collection entity that aggregates all sub‑directory material**

@drexel_historical_records:collection {description: "Aggregated archival material from Drexel University (1861‑1863) covering commencements, faculty meetings, and miscellaneous college documents.", date_range: {start: @date_1861, end: @date_1863}}

@file_pinax -> part_of -> @drexel_historical_records  

**5. Synthesize – link the collection to the major events and documents from each subdirectory**

@drexel_historical_records -> includes -> [@commencement_1861:event, @faculty_meeting_oct_10_1861:event, @faculty_meeting_oct_17_1861:event, @faculty_meeting_feb_6_1862:event, @faculty_meeting_feb_13_1862:event, @faculty_meeting_sept_13_1862:event, @faculty_meetings_1863:event, @miscellaneous_documents:document]

**6. Map recurring participants across the aggregated material**

@a_preston -> participated_in -> [@commencement_1861:event, @faculty_meeting_oct_10_1861:event, @faculty_meeting_oct_17_1861:event, @faculty_meeting_feb_6_1862:event, @faculty_meeting_feb_13_1862:event, @faculty_meeting_sept_13_1862:event, @faculty_meetings_1863:event]  

@dr_fussell -> participated_in -> [@commencement_1861:event, @faculty_meeting_oct_10_1861:event, @faculty_meeting_oct_17_1861:event, @faculty_meeting_feb_6_1862:event, @faculty_meeting_feb_13_1862:event, @faculty_meeting_sept_13_1862:event, @faculty_meetings_1863:event]  

@dr_kerr -> participated_in -> [@commencement_1861:event, @faculty_meeting_oct_10_1861:event, @faculty_meeting_oct_17_1861:event, @faculty_meeting_feb_6_1862:event, @faculty_meeting_feb_13_1862:event, @faculty_meeting_sept_13_1862:event, @faculty_meetings_1863:event]  

@dr_temple -> participated_in -> [@commencement_1861:event, @faculty_meeting_oct_10_1861:event, @faculty_meeting_oct_17_1861:event, @faculty_meeting_feb_6_1862:event, @faculty_meeting_feb_13_1862:event, @faculty_meeting_sept_13_1862:event, @faculty_meetings_1863:event]  

@dr_locatis -> participated_in -> [@faculty_meeting_feb_6_1862:event, @faculty_meeting_feb_13_1862:event, @faculty_meeting_sept_13_1862:event]  

@dr_birdsell -> participated_in -> [@faculty_meeting_oct_10_1861:event, @faculty_meeting_oct_17_1861:event]  

@edwin_fassell -> participated_in -> [@faculty_meetings_1863:event]  

@c_h_j_scarlett -> participated_in -> [@faculty_meetings_1863:event]  

**7. Define the subject‑concepts referenced in the collection’s metadata (if not already present)**  

@commencement:concept {field: "College ceremony"}  
@graduation:concept {field: "Degree conferral"}  
@education:concept {field: "Higher education"}  
@voting:concept {field: "Balloting in academic bodies"}  
@nineteenth_century:concept {period: "1800‑1899"}  
@faculty_meetings:concept {field: "Academic governance"}  
@resignations:concept {field: "Faculty turnover"}  
@college_administration:concept {field: "Institutional management"}  
@medical_education:concept {field: "Training of physicians"}  
@academic_appointments:concept {field: "Faculty hiring"}  
@medical_theses:concept {field: "Student research"}  
@college_organization:concept {field: "Structural layout"}  
@academic_administration:concept {field: "Curricular oversight"}  
@college_governance:concept {field: "Policy making"}  
@historical_documents:concept {field: "Archival records"}  

**8. Link the collection’s subjects to these concepts**

@drexel_historical_records -> covers -> [@commencement:concept, @graduation:concept, @education:concept, @voting:concept, @nineteenth_century:concept, @faculty_meetings:concept, @resignations:concept, @college_administration:concept, @medical_education:concept, @academic_appointments:concept, @medical_theses:concept, @college_organization:concept, @academic_administration:concept, @college_governance:concept, @historical_documents:concept]

**9. Add the geographic locations cited in the metadata (new place entities where needed)**  

@peoria_il:place {city: "Peoria", state: "Illinois", country: @united_states}  
@quincy_ma:place {city: "Quincy", state: "Massachusetts", country: @united_states}  
@germantown_pa:place {city: "Germantown", state: "Pennsylvania", country: @united_states}  
@baltimore_md:place {city: "Baltimore", state: "Maryland", country: @united_states}  
@camden_nj:place {city: "Camden", state: "New Jersey", country: @united_states}  
@san_francisco_ca:place {city: "San Francisco", state: "California", country: @united_states}  
@irving_mills_ny:place {city: "Irving Mills", state: "New York", country: @united_states}  
@coylean_in:place {city: "Coylean", state: "Indiana", country: @united_states}  

**10. Connect the collection to these places (reflecting the “place” array in the metadata)**  

@drexel_historical_records -> associated_with -> [@medical_fund_hall, @hospital_building, @philadelphia, @peoria_il, @quincy_ma, @germantown_pa, @baltimore_md, @camden_nj, @san_francisco_ca, @irving_mills_ny, @coylean_in]  

**11. Synthesis – illustrate the temporal span of the collection**

@date_1861_1863:date {start: @date_1861, end: @date_1863}  
@drexel_historical_records -> time_span -> @date_1861_1863
