Hours live in the roster row and refresh on the cache interval. Daily caches catch most operational changes; for blood-shortage campaigns with rolling extended hours, drop the cache to an hour or trigger a manual cache flush after each schedule edit.

Yes, as a sibling page group. Use a /blood-drives/{slug}/ pattern with one row per drive (venue, date, time window, host org, appointment URL). The fixed-center pages link to upcoming drives in their city via an additional selector that pulls a filtered subset of the drives source.

Yes. Place JSON-LD on the base page with the appropriate schema type and use mappings to inject name, address, telephone, openingHoursSpecification, and medicalSpecialty per row. Rich results sometimes surface hours and address directly in SERPs for high-intent donor queries.

Most blood banks use scheduling tools (Hemasphere, Donor Studio, BloodHub, or vendor portals) that support deep linking to a specific center. Store the deep-link URL per center in the roster and render via a selector mapping on the primary CTA, so the donor lands one click away from booking.

Yes. Add a flags array column for CMV-negative recruitment, double red eligibility, or HLA-matched platelet programs, then render flags via list mappings. Some centers focus on specific rare needs, and surfacing that to donors who match makes the recruiting more efficient.

Maintain a shared eligibility content block on the base page covering age, weight, medication waitlists, and travel deferrals. Center-specific deferrals (such as a center temporarily pausing platelet collections) live as a row field rendered via a selector mapping as a notice banner.

Yes. Define an additional page group like /blood-donation/type/{slug}/ for whole-blood, platelets, plasma, and double-red index pages. The per-center pages stay primary; index pages capture donor-type-first queries and link out to centers that offer each type.

Add a status field (open, paused, emergency-closure) and an optional banner_text column, rendered via meta and selector mappings. A center paused due to weather should show a clear notice without a 404, since donors may have appointments to reschedule.
