Welcome to my professional portfolio repository. I am a current Master of Library and Information Science (MLIS) student specializing in archives, preservation, and community-centered digital stewardship.
This repository documents archival technology workflows demonstrating metadata design, digital preservation practices, audiovisual description, web archiving methodologies, and digital collections development.

- Metadata & Description Standards: DACS, EAD XML, PBCore, Dublin Core, Homosaurus Vocabulary
- Digital Preservation Workflows: BagIt (RFC 8493), SHA-256 fixity verification, provenance documentation, technical metadata extraction
- Web Archiving: WARC capture, replay validation, born-digital appraisal workflows
- Systems & Platforms: ArchivesSpace, Omeka Classic/S, GitHub Version Control
- Web Development: HTML5, CSS3, JavaScript
This repository contains reproducible archival workflows demonstrating practical applications of digital preservation, metadata standards, digital collections management, and web-based access systems.
Focus: Audiovisual metadata creation and technical description using PBCore.
Workflow demonstrates:
- Mapping descriptive, structural, and technical metadata for digitized audiovisual materials
- Documenting relationships between original physical carriers and digital derivatives
- Applying community-centered descriptive practices using Homosaurus terminology
Tools & Standards: PBCore XML, ffprobe technical characterization, Git version control
Focus: Digital preservation ingest and fixity verification using BagIt.
Workflow demonstrates:
- Creating structured preservation packages using the Library of Congress BagIt specification (RFC 8493)
- Generating and validating SHA-256 checksums
- Recording provenance, workflow documentation, and validation results
Tools & Standards: BagIt, SHA-256 fixity checks, Bagger, preservation documentation
Focus: Capturing and preserving born-digital community records.
Workflow demonstrates:
- Appraisal and selection of web-based cultural materials
- WARC capture and preservation documentation
- Replay validation and ethical considerations for community digital records
Tools & Standards: ArchiveWeb.page, ReplayWeb.page, WARC
Focus: Digital collections management and exhibit development using Omeka Classic.
Workflow demonstrates:
- Building a locally hosted digital collections environment using MAMP, Apache, PHP, and MySQL
- Creating item records and applying Dublin Core metadata to archival digital objects
- Organizing digital materials into collections and constructing a public-facing digital exhibit
- Documenting the relationship between archival materials, digital surrogates, and interpretive storytelling
- Tools & Standards: Omeka Classic, Dublin Core Metadata Element Set, MAMP, MySQL, phpMyAdmin
Focus: Digital public history, metadata design, and community-centered digital collections development using Omeka S.
SCLAP is a digital public history project documenting Southern California lesbian histories through archival research, structured metadata, controlled vocabularies, and place-based discovery.
Workflow demonstrates:
- Designing Omeka S Resource Templates for digital objects, people, organizations, and historic community spaces
- Applying Dublin Core metadata standards within a digital collections environment
- Developing metadata schemas that balance linked-data authority terms with community-specific description
- Implementing controlled vocabularies using Homosaurus linked-data terms and SCLAP-specific subject terminology
- Documenting metadata decisions, archival sources, and descriptive practices
- Building a sustainable digital collections workflow using open-source tools
Tools & Standards: Omeka S, Dublin Core Metadata Element Set, Homosaurus Vocabulary, controlled vocabularies, Docker, GitHub Version Control

These case studies focus on the intersection of technical infrastructure and ethical archival practice, particularly within community-based collections. Each workflow emphasizes sustainable preservation practices while maintaining the historical context and cultural meaning of archival materials.
