Working toward a new
Copyright Agreement
between SATA-IO and T13
The Issues
• The schedules for updating T13 and SATA-IO standards are
not synchronized
• Currently there must be re-negotiation for a new agreement for
every combination of T13 and SATA-IO revision
• Sometimes T13 documents are split into multiple pieces over
time, so new copyright agreements are needed
• It would simplify matters for both groups if a broader agreement
could be made, not tied to specific document revisions
• Section numbers often change between revisions, so tie the
license to classes of content instead

Record of working together
• T13 and SATA-IO successfully negotiated copyright
agreements for:
• SATA Revision 1.0a for ATA/ATAPI-7
• SATA Revision 2.5 for ATA8-ACS
• SATA Revision 2.6 for ACS-2
• T13 has domain over ATA commands that are defined for all
device types (e.g. the Application layer) and for everything
dealing with PATA
• SATA-IO has domain over SATA-only commands and all other
interface layers (Phy, Link,Transport,Command)
• Many companies belong to both organizations
• T13 and SATA-IO have synchronized updates to the other
group’s standards with their own

The Proposal
• A new agreement is needed by T13 to include some
SATA Revision 3.0 material into ACS-3
• Make the agreement not restricted to specific T13
standards, but for any T13 standard
• Make the agreement reference content “classes”
instead of specific document section numbers
