Schedule a nightly sync that pulls the Hackage 00-index tarball, diffs against the previous run, and updates only changed rows. SleekRank regenerates the affected pages. The full corpus is incremental, so sync stays fast as the registry grows. The dateModified field on each row drives the JSON-LD payload so search engines pick up freshness signals without manual editing.

Yes. Hackage allows metadata edits to a published version without bumping the version. Store a revisions count per version in the versions JSON array. The release timeline renders both the original release and any subsequent revision count, with a link to the metadata diff. Readers debugging build failures see at a glance whether a revision changed the version bounds.

Add a stackage_lts JSON array of LTS resolvers that include the package. A list mapping renders a Stackage compatibility block on each page with the LTS version range. Readers using Stackage-based projects see immediately which resolvers carry the package, and the index page at /haskell/hackage/stackage-lts/{resolver}/ lists every included package.

A deprecated boolean and a successor field per row. Deprecated packages render a warning banner on every page with the recommended successor linked. The sitemap keeps the URL alive so external code still resolves, but search engines see the dateModified update and reindex with the deprecation context surfaced in the title and meta description automatically.

Yes. Cross-reference the Hackage Matrix build report data per package per GHC version and store it as a build_matrix JSON object. A heat-map block on each page renders the matrix visually. Readers see at a glance which GHC versions build cleanly and which fail, without leaving the package page to check the upstream matrix UI directly.

Each page carries a unique description, unique version history, unique dependency table, unique GHC compatibility data, and a unique changelog reference. That is genuinely unique data per page. Search behavior matches npm and crates.io listings, which rank reliably across thousands of pages because every entry is genuinely distinct and updated as releases ship to the registry.

Yes. Each package carries category strings from its Cabal file. SleekRank generates /haskell/hackage/category/{category}/ index pages ranked by recent downloads or last-updated date. Keyword-based clusters can be added by parsing description text or by maintaining a curated keyword overlay file alongside the registry-sourced dataset for editorial control.

Append the new GHC version to ghc_versions on every package that builds against it as build reports come in. The compatibility badges and the /haskell/hackage/ghc/{version}/ index page update on the next sync. Editor cost per new GHC release is one configuration field. Packages that fail against the new GHC carry a clear incompatibility note driven by build matrix data.
