Actors

(A1) Scientific Community Center Site

Manager (CCSM)

Prerequisites

(P1) Federated infrastructure approach

(Dependencies,

(P2) Each data object has unique PID

(Assumptions)

(P3) Data access permissions remain

(P4) Federated AAI concepts adopted

Steps

(S1) Create policy P for M replications

(S2) Specify the target data centers C

(S3) Exclude centers X from policy

(S4) Define replicated data lifetime T

(S5) Policy is saved and executed

(S6) Policy-based replication is done

(S7) Data objects are safely replicated

(S8) Replicated data stored in local

Long-term Archives (LTAs)

Variations

(V1) Existing policy P might be

updated by the CCSM

(V2) Additional manual data

replication if needed by the CCSM

Quality

(QA1) Reliability of replication

Attributes

(QA2) More optimal data curation

(QA3) Better accessibility of data

Non-functional

(NF1) Usability for creating and

executing the replication policy

Issues

(I1) Federated AAI concepts work

still work-in-progress
