Free tier	50 GB and 100 files per record by default; 10 GB per file. Quota increase is granted on email request to researchdata@kth.se. Not a hard wall — a record with a 70.4 GB single object exists in the public API, i.e. increases are real and granted. unit objects; metered on unstated
Price	none stated
Limits	per-object-cap (binding) 10 GB per file source 100 files per record by default. 'For data governance reasons ... all data must belong to at least one community.' Files immutable after publication; one-month grace period.
Identity	institution institution
Egress	Free and anonymous. Downloads 302 to presigned.s3.cloud.kth.se with X-Amz-Expires=60 — sixty seconds: re-resolve per request or watch every parallel GET return an empty 302.
Per-object cap	10 GB per file (10000000000 bytes)

Interface	rest InvenioRDM REST (/api/records), OAI-PMH, GitHub integration.
Tooling	curl; the InvenioRDM python client.
Composes with	Mountable via any InvenioRDM wrapper; the 60-second presign makes it a poor CDN origin unless fronted by Cloudflare with a re-resolving shim.
Reliability	Login is ORCID / GitHub / KTH SSO — genuinely open — but deposit requires membership of a KTH community, and the quota-increase email asks which 'organisation, project, or grant' the data belongs to.

Composes with	The out-of-Sweden exception is the only explicit statement found anywhere that a person based abroad can hold a Swedish allocation, and it still requires a Swedish group.
Reliability	no reliability event recorded
Notes	The condition is a Swedish research group or supervisor, so the door is a collaboration rather than an application. PDC publishes no size for the small test allocation, so the field is null.
