Iiif Bundle Laravel Package

Technical Evaluation

• Architecture fit: survos/iiif-bundle is a Symfony bundle for IIIF functionality, not a Laravel-native package. Direct fit is strong only for Symfony applications; for a Laravel/PHP stack, treat it as an external IIIF service or a porting candidate rather than an installable Laravel dependency.
• Integration feasibility: Feasible for Symfony via Composer and bundle registration. Laravel feasibility is medium-to-low without an adapter because Laravel does not natively consume Symfony bundles. A Laravel integration would likely require exposing the bundle through a separate Symfony service, wrapping underlying IIIF libraries, or porting configuration/routes/services.
• Technical risk: High until package metadata is inspected. The 1.0.0 release notes only state “not yet in survos mono” and provide no feature, compatibility, or breaking-change detail. That suggests a packaging/versioning milestone rather than validated production readiness. Key unknowns include PHP/Symfony version constraints, IIIF Image/Presentation API support, auth/CORS behavior, storage drivers, and whether the release is actually synchronized with the Survos monorepo.
• Key questions: Which PHP and Symfony versions are supported? Does it implement IIIF Image API 2.x/3.x and Presentation API 2.x/3.x? Is it bundle-coupled or usable as decoupled services? What does “not yet in survos mono” imply for support, CI, and release provenance? Is there a documented Laravel path, or would we own a bridge? What is the license and maintainer activity?

TPM position: Conditional interest for Symfony-based IIIF work; not recommended for direct Laravel adoption without a spike and explicit adapter/service decision.

Integration Approach

• Stack fit: Use directly only in a Symfony application or a standalone PHP service built around Symfony components. For Laravel, prefer a service-boundary integration: run IIIF endpoints in a separate Symfony container and call them from Laravel over HTTP, or reuse underlying IIIF libraries rather than embedding the bundle.
• Migration path: Start with an isolated proof of concept outside the Laravel monolith. If the bundle works, expose image/manifest endpoints as a small IIIF service. If a Laravel-native path is mandatory, map bundle configuration to Laravel config, Symfony routes to Laravel routes, and bundle services to Laravel container bindings only after validating the underlying classes are framework-agnostic.
• Compatibility: Pin survos/iiif-bundle:1.0.0 only after checking composer.json for PHP, Symfony, and PSR dependency constraints. Do not assume Laravel compatibility from the 1.0.0 tag. Validate against the target Laravel/Symfony/PHP matrix before committing.
• Sequencing: 1) Verify package metadata, license, CI, and release provenance. 2) Run a Symfony-only spike with sample images and manifests. 3) Validate IIIF compliance and auth/CORS/storage behavior. 4) Decide external service vs. Laravel adapter. 5) Build the adapter behind a feature flag if needed. 6) Roll out with fallback to existing image delivery.

Operational Impact

• Maintenance: Two-ecosystem maintenance risk is significant. If Laravel uses a bridge, the team owns compatibility with both Laravel and the Symfony bundle. The “not yet in survos mono” note may indicate release/monorepo process immaturity, so dependency updates should be watched closely.
• Support: Release notes provide little operational evidence. Require docs, issue-tracker activity, maintainer responsiveness, and a support path before production use. IIIF compliance issues can be subtle and need upstream clarity.
• Scaling: IIIF image processing, tiling, thumbnails, and manifest generation can be CPU-, I/O-, and storage-intensive. Plan for queue workers, caching, CDN delivery, and possibly a dedicated image server such as Cantaloupe rather than assuming the bundle alone solves scale.
• Failure modes: Common risks include image-processing failures, invalid or incompatible manifests, CORS/auth misconfiguration, storage-path and cache-invalidation issues, Symfony/Laravel version drift, and dependency conflicts. Thin release notes increase the chance of undisclosed breaking behavior.
• Ramp-up: A Symfony-experienced PHP team can ramp up reasonably; a Laravel-only team needs additional IIIF and Symfony bundle context. Budget a discovery spike and compliance testing before estimating delivery.
