Framework09

MODAVIS FrameworkDevelopmentCoordinates the shared contracts and responsibilities of the MODAVIS research workflow.

Multimodal Organological Data Analysis and Virtualization Systems connects acquisition, interpretation, public access and preservation. The framework coordinates components; it is not an additional acquisition application.

InitiatorCore componentOwns shared schemas, migrations, integrity constraints and data governance.

Establishes the relational structures that other components use. Runs in the research environment; a public web service is not offered.

AggregatorCore componentRegisters and acquires approved sources, retaining source records, media and transfer evidence.

Preserves source-native evidence and prepares documented transfers. Canonical reconciliation and projection belong to the Processor workflow.

ProcessorCore component · development 0.2.0Stages evidence and coordinates normalization, analysis and controlled canonical projection.

Its twelve modules keep source observations, candidate assertions, review decisions and accepted projections distinct. The cohesive 0.2.0 package is a development candidate, not a verified public release.

ProspectorCore componentDiscovers literature, media, authority records and other candidate evidence.

Search results remain provisional. Prospector does not write directly to canonical research records.

NavigatorPublished · 1.0.0Provides public, source-aware exploration of instruments, people, places and their relationships.

Exposes research projections, provenance and citations. Public browsing is separate from administrative operations.

PersistorCore componentPackages approved research outputs for preservation, deposition and persistent identification.

Release preparation includes metadata, rights and fixity checks. Packaging a candidate does not itself authorize publication.

MonitorDevelopment · read-onlyCollects component status, freshness and historical observations for research operators.

An independent observer of explicitly permitted status sources. It does not execute jobs, repair services or change canonical data.

musiXplora BridgeDevelopment · internal toolImports and explores versioned musiXplora person snapshots with faceted search.

Connects a specialist biographical source to research inspection workflows. It is an internal application, not a publicly deployed discovery service.

Processor modules12

IngestorProcessor moduleValidates acquired transfer records and stages them without discarding their source structure.

Passing a transfer schema establishes structural validity; it does not constitute acceptance into the canonical corpus.

NormalizerProcessor moduleDerives deterministic normalization and reconciliation candidates from staged evidence.

Retains original observations. Review and canonical projection remain explicit subsequent decisions.

BootstrapProcessor moduleApplies versioned policy to observations and decisions, producing atomic projection receipts.

Canonical projection requires owner authorization and frozen dependencies; it is not an unrestricted import shortcut.

Document evidenceProcessor moduleExtracts source-bound pages, assets, text selectors and candidate assertions from identified documents.

Quotations and derived statements retain exact document evidence and provenance.

LocalizerProcessor moduleRanks geographic proposals from place mentions and provider evidence.

Preserves ambiguity, temporal qualifications and coordinate accuracy rather than silently treating a place guess as a precise location.

Language detectionProcessor moduleProduces language-detection evidence and quality checks for source text.

Uncalibrated scores remain qualified, and insufficient evidence can result in abstention.

LitparserProcessor moduleTurns citation text into structured literature candidates with literal field evidence.

Unknown dates, pages and other fields remain uncertain. Candidate parsing does not write canonical records.

EnrichmentProcessor moduleCollects reviewable institution and virtual-instrument facts from authorized source pages.

Fetching is opt-in and source evidence is retained for replay and review.

PLENUMProcessor moduleModels claim-specific evidence suitability, dependencies and uncertainty.

Provenance-Linked Evidence Network for Uncertainty Modeling considers transmission and evidence independence. Its scores are not calibrated probabilities or universal source-trust ratings.

AmbitusProcessor moduleExtracts nominal pitch-range evidence from MusicXML, MXL and MIDI.

Reports pitch-control qualifications. It does not establish an instrument’s identity, acoustic range or performed sound.

ImagesegProcessor moduleProduces aligned image masks and annotation artifacts using SAM 2.

Segmentation is class-agnostic and requires interpretation. A mask does not by itself classify a pipe, keyboard or stop.

ModelgeneratorProcessor moduleReconstructs point clouds and camera paths from source photograph bundles using a pinned Depth Anything 3 workflow.

Point clouds are a complete supported output. A textured mesh is not guaranteed. This photographic workflow is distinct from parametric pipe reconstruction in VAO-Pipe.

Specialist tools09

OrgRecPublished · 0.3.2A macOS application for structured organ recording, audio analysis and VAO export.

The 0.3.2 release adds independent audio analysis with waveform, spectrogram, pitch and partial views, plus documented exports. It supports VAO 0.5 export and a verified offline POD 1.6 projection; individual source identities remain explicit.

OrgMapPublished · 0.1.0A geographic interface for discovering pipe organs in MODAVIS data.

Map locations and source qualifications should be read together; geographic display does not imply survey-grade precision.

vaoXRPublished · 0.1.0A browser-based environment for inspecting and interacting with Virtual Acoustic Objects.

Available experiences depend on the package’s declared capabilities, the viewer version and browser support. Not every package offers playback, XR or simulation.

ScriptorPublished · 0.1.0Assists local transcription of photographed organ stop labels and other image text.

Retains image crops and raw OCR for manual review. Corpus matches are suggestions, not automatic substitutions. The archived 0.1.0 workflow uses POD 1.5; this is distinct from later POD releases.

midiAuralizerResearch softwareRenders Standard MIDI Files through virtual instruments for reproducible offline auralization.

Records rendering choices and paradata so that a derived audio file can be related to its MIDI and virtual-instrument inputs. No fixed public release was verified in this audit.

bellcast-webuiAssociated research pilotCombines modal bell synthesis, urban auralization and an interactive 3D web view.

A web application and FastAPI backend developed around the Landshut Propstglocke case, including 3D Tiles. Modelled propagation and synthesis depend on declared assumptions; no fixed public software release was verified.

VAO-PipeEvaluation release · 0.1.0Reconstructs measured organ pipes and evaluates their passive pressure-acoustic eigenmodes.

The report covers 18 open labial pipes from the Cuntz, Silbermann and Welte instruments. Measured dimensions drive procedural geometry. Passive eigenmode analysis is not a complete aerodynamic model of a sounding pipe.

PAMTConceptual architectureOutlines a Photogrammetric-Acoustical Modeling Toolkit linking geometry, material interpretation and room-acoustic modelling.

A methods architecture and research roadmap. The thesis does not establish an implemented, end-to-end field-validated software pipeline.

Workflow demonstrationsPublished · 0.1.1Provides containerized demonstrations of Initiator, Aggregator, Processor, Prospector and Persistor.

A reproducibility and review environment for five backend components, not a deployment of the complete live research system.

VAO implementations05

VAO CLIArchived 0.2.0 · development 0.3.1Resolves DOI releases, inspects metadata and fixity, and materializes selected VAO resources locally.

The archived 0.2.0 release targets VAO 0.4. Newer 0.3.1 development supports the final 0.4 and 0.5 lines. Bounded remote retrieval, integrity checks and local caching remain distinct from depositing a release.

VAO Importer for UnityArchived · 0.6.0-rc.1Imports VAO carriers into Unity for supported media, interaction, MIDI and XR workflows.

The current 0.6.0-rc.4 development line targets Unity 6, final VAO 0.4 and a pinned 0.5 candidate. Support is profile- and platform-dependent; this does not imply blanket compatibility with every final 0.5 package.

VAO BlenderPublished · 0.4.0-rc.2Validates and inspects VAO packages in Blender and materializes verified embedded GLB geometry.

Supports final VAO 0.4 and a pinned 0.5 candidate. Modern package inspection is distinct from the fuller legacy interaction path for VAO 0.2.2.

VAOMVAO reference toolsThe Virtual Acoustic Object Manager provides Python reference utilities within the VAO standard tooling.

A reference library and tool family accompanying the specification. VAOM and the independently versioned VAO CLI should not be treated as the same release.

OrgRecCoreLibrary within OrgRecImplements core package and validation functionality in Swift for OrgRec.

An independent implementation embedded in the OrgRec project, not a separately verified application release.

Standards & semantics03

Virtual Acoustic Object StandardPublished · 0.5.0Defines an exchange and preservation contract for multimodal digital musical instruments.

Specifies layers, conformance profiles, bootstrap and preservation carriers, distributions and fixity. A standard version and a particular instrument-package version are separate identifiers.

MODAVIS Ontology NetworkPublished · 0.1.0Models instruments, historical states, components, evidence and controlled vocabulary relationships.

Uses OWL, SKOS and SHACL to make identities, assertions and constraints explicit.

OMAROPublished reference dataset · 0.1.0Connects multiperspective organological assertions and review with reference classifications and multilingual instrument names.

The cited deposit is the OMARO reference dataset, including Hornbostel–Sachs classifications. Its dataset release should not be confused with the entire MODAVIS Ontology Network.

Research collections08

Pipe Organ Dataset (POD)Public release · 1.6.0A versioned research corpus connecting organs, actors, places, source accounts and virtual instruments.

The release contains 215,769 canonical organs. These are corpus counts, not a census of all surviving organs.

POD reviewer preservation packageRestricted · 1.5.0Preserves additional research and source materials for controlled scholarly access.

This is the older 1.5.0 preservation package. It does not establish a version-identical reviewer edition of public POD 1.6.0.

AAMIRPublished · 1.0.0The Audio, Acoustics, and Musical Instruments Repository Index surveys 403 repositories in 15 primary categories.

A curated research dataset about external software and algorithms; inclusion does not make those third-party projects MODAVIS software.

Organological source cataloguePublished · 2026-09-11-revisedCritically documents organological databases, portals and repositories.

A research guide to source coverage and methodological differences; it is separate from the integrated POD corpus.

Digital heritage project synopsisPublished corpusCompares international digital cultural heritage and sound-digitization projects.

A systematic comparative research corpus, not a directory of software authored by MODAVIS.

Organ virtualization methods corpusPublished corpusDocuments methods and systems for pipe-organ digitization, virtualization and sound modelling.

Brings together a methodological taxonomy, systems catalogue and supporting research corpus.

VPO reference and timbre corpusThesis reference · availability unverifiedSupports the research comparison of virtual pipe-organ instruments and their timbres.

Listed in the thesis publication register. The cited deposit was not retrievable through the public metadata registry during the 26 September 2026 audit, so no verified download is offered here.

VPO inventory and availability auditPublished · 0.1.0Records the provisional OrgRec virtual pipe-organ collection and source availability.

An inventory and availability assessment; it does not grant rights to every listed sample set.

Reference objects05

Cuntz Positiv · 1610VAO package · 0.5.0-rc.2A reference Virtual Acoustic Object for the historical Cuntz positive organ.

Connects the instrument’s documented structure and media in a versioned package; also contributes measured pipes to VAO-Pipe.

Silbermann Brüstungspositiv · 1722VAO package · 0.5.0-rc.2A reference Virtual Acoustic Object for the Gottfried Silbermann positive organ.

The package release is independently versioned from the VAO standard and contributes measured pipes to VAO-Pipe.

Welte cinema organ · 1928VAO package · 0.5.0-rc.2A reference Virtual Acoustic Object for the Welte cinema organ.

The Kinoorgel record supplies a versioned research object and contributes measured pipes to the pipe evaluation.

Landshut Propstglocke · 1767Associated research caseConnects bell documentation and digitization to the bellcast synthesis and urban-auralization pilot.

The thesis lists a data-package deposit, but its public metadata could not be verified during the audit. A download is not implied.

Ariston · 1882Research caseA mechanical-musical-instrument case in the thesis’s study of digital representation and interaction.

A documented research case rather than a separately verified public software release or VAO deposit.

Predecessors & support04

Zenodo ToolboxPredecessor · 2024Automates Zenodo metadata checks, batch deposition and OAI-PMH harvesting.

A preceding toolkit in the development of the project’s deposition workflows.

Heritage Data ProcessorPredecessor · 2025Organizes processing and conversion workflows for heterogeneous cultural-heritage data.

Uses stateful .hdpc project files for replayable processing.

WebHDP / HPC-LinkPredecessor · 0.1.0-alpha.1Connects web-based heritage-data workflows to asynchronous high-performance computing.

HPC-Link is an integration within this tool family. It delegates compute-intensive 3D and audio tasks; it is not an additional MODAVIS core component.

Legacy processing helpersHistorical support toolingThe earlier standalone Ingestor, marker-hpc and 3drepo-xlsx-to-draco supported ingestion, document processing and compute transfers.

Retained as development references. The older standalone Ingestor is distinct from the current Processor Ingestor module; these helpers are not presented as maintained public applications.

Publication channels02

MODAVIS on ZenodoCurated communityCollects related research data, software, standards and publications.

Community membership is a discovery aid; cite a specific version record when reusing an artifact.

Virtual Acoustic Objects on ZenodoCurated communityCollects VAO reference packages and related work.

Discovery through a community does not replace verification of a package’s version, rights and fixity.
