Public access is not the same as permission to republish. This register separates factual observations and links from documents, recordings, and derived text whose reuse rights remain unresolved.
Reading the register
Four separate questions
Who issued it?The government body, platform, author, or project responsible for the material.
What is published here?The exact metadata, text, relation, or derived record exposed in this release.
What may be redistributed?The project’s conservative boundary—not a substitute for permission or legal advice.
Why?The official rule, terms page, or unresolved authorship issue supporting that boundary.

9 source families
Reviewed 2026-07-27. Controlled values and full field definitions are in the data dictionary.
Michigan Senate or House media publisher and CASTUS
CASTUS-hosted legislative media
Platform terms restrict reuse
Content classes
House and Senate recordings hosted through CASTUS
Domains
cloud.castus.tv
Published here
Video identifiers, titles, source links, durations, proceeding associations, and project-generated transcript search text appear in the public database. Video files are not redistributed.
Redistribution boundary
Link and metadata only for the hosted recording. Downloaded media and full derived transcripts remain pending publisher and platform review.
Basis
No source-specific open license or affirmative redistribution grant was located during review.
Attribution
Source recording linked through the official legislative publisher's CASTUS service; no endorsement is implied.
Obtain publisher/platform confirmation before distributing recordings or full transcripts derived from them.
Public member and service records retain source profile URLs and portrait-image URLs. The project does not include local copies of those pages or images in release artifacts.
Redistribution boundary
Link and factual identity/service metadata only. Page text, branding, and images are not approved for republication without source-specific permission or another applicable legal basis.
Basis
Caucus and member-branded websites do not share a single observed open license, and may contain party, campaign, photographer, or vendor material distinct from official legislative records.
Attribution
Member profile or image linked to the publishing caucus or member office; no endorsement is implied.
The pipeline should eventually record publisher and license terms per profile/image URL rather than relying on this conservative family default.
member profiles; schedules; committee meetings; minutes; agendas; testimony; audio and video
Domains
house.mi.gov, www.house.mi.gov
Published here
Structured facts, official links, hashes, media metadata, and project-generated transcript search text appear in the public database. Source documents and recordings are not included as bulk artifacts.
Redistribution boundary
Metadata, factual observations, hashes, and links may be published. Document bodies, recordings, and derived transcript redistribution remain pending source-specific review.
Basis
No source-wide open license was located. Legislative Council Act provisions preserve State interests in legislative information, and some committee files contain third-party submissions.
Attribution
Source: Michigan House of Representatives. Linked materials remain subject to their source-specific rights.
The register does not assume that House-hosted content is wholly government-authored or freely redistributable.
Structured facts, identifiers, official links, hashes, and bounded evidence excerpts appear in the public database. Full official documents are linked rather than republished.
Redistribution boundary
Metadata, factual observations, project classifications, hashes, and short source-located excerpts only. No grant to redistribute the underlying official documents is asserted.
Basis
MCL 4.1204 through 4.1204f require Internet availability while expressly preserving State copyright and other proprietary interests.
Attribution
Source: Michigan Legislature. This independent project is not an official State of Michigan publication.
Internet availability and fee-free access are not treated as an open license. Final publication policy requires legal review.
Structured facts, official links, hashes, media metadata, and project-generated transcript search text appear in the public database. Source documents and recordings are not included as bulk artifacts.
Redistribution boundary
Metadata, factual observations, hashes, and links may be published. Document bodies, recordings, and derived transcript redistribution remain pending source-specific review.
Basis
The official Senate disclaimer describes the site as a public service but states Copyright 2026, all rights reserved, and warns that some content comes from external sources.
Attribution
Source: Michigan Senate. This independent project is not endorsed by the Senate.
Third-party testimony and attachments require a separate authorship review even when hosted by the Senate.
The public database and curated table exports contain project-created selection, arrangement, classifications, and documentation alongside source-derived facts.
Redistribution boundary
Research inspection and citation are supported. No software, database, or compilation license is granted while the manifest says NOASSERTION.
Basis
The repository has not yet adopted separate software and data licenses. The release manifest therefore records SPDX NOASSERTION.
Attribution
Michigan Legislative Activity Ledger, release-specific citation required; preserve source attributions and uncertainty states.
A later license decision must not retroactively imply rights in third-party source content.
Michigan Legislative Activity Ledger research project
Project-generated automated transcripts
Third-party rights unresolved
Content classes
automated speech-to-text segments; timestamps; model metadata
Domains
local research pipeline
Published here
Transcript segments and timestamps are available for search and API inspection in the public SQLite read model. No standalone transcript bulk package is published.
Redistribution boundary
Publication is provisional and source-dependent. Do not redistribute full transcripts until the underlying recording rights and legal basis are reviewed.
Basis
The transcript files are project-generated, but they are derived from recordings whose source-specific rights are not uniformly resolved.
Attribution
Automated transcript generated by the Michigan Legislative Activity Ledger; verify against the linked source recording.
Automated text can contain recognition, timing, and speaker errors. Search access is not a representation that reuse rights are cleared.
Document metadata, official links, content classifications, measure relations, and reviewed member attributions appear in the public database. Normalized bodies are withheld.
Redistribution boundary
Metadata, factual relations, hashes, and links only. Full text and files are excluded until authorship and permission are established.
Basis
Hosting by a legislative body does not establish government authorship or a license from the submitting author.
Attribution
Source document linked from the relevant Michigan House or Senate committee record; rights may belong to the submitting author.
This family is separated from government-authored minutes and agendas because the rights analysis differs.
Video identifiers, titles, official source links, durations, proceeding associations, and project-generated transcript search text appear in the public database. Video files are not redistributed.
Redistribution boundary
Link and metadata only for the hosted recording. Downloaded media and full derived transcripts are not approved for redistribution unless a specific upload is separately licensed or permission is obtained.
Basis
YouTube's standard terms restrict downloading, reproducing, and distributing content except through service features, permission, or applicable law. Individual uploads may instead use CC BY.
Attribution
Source recording linked through YouTube; rights remain with the uploader and applicable rights holders.
The pipeline does not currently preserve a per-video YouTube license observation; therefore it applies the conservative default.
