Dear Dispatch Working Group,

I am submitting this request for the scheduling of a new Internet-Draft as an Individual Submission. The draft defines a proposed protocol named DACP: Data Access and Collaboration Protocol.

The details of the submission are as follows:

- Draft Name: draft-shenzhihong-dacp-00
- Title: DACP: Data Access and Collaboration Protocol
- Authors: Zhihong Shen ,"><bluejoe@cnic.cn>, Xiaojie Zhu<xjzhu@cnic.cn>
- Intended Working Group: Individual Submission
- Abstract: This document describes the Data Access and Collaboration Protocol
(DACP), a communication protocol designed to support cross-node,
cross-process data access in scientific and distributed computing
environments. DACP provides standardized streaming-based data
interactions over the Arrow Flight protocol and defines a unified
Streaming DataFrame (SDF) model, which acts as a high-performance
abstraction for accessing and processing both structured and
unstructured data.
- IPR Status: No IPR disclosures relevant to this draft have been submitted.
- Expiration: 6 months from submission

Additional Notes:
- The draft is ready for initial publication and review.
- The authors request guidance from the Dispatch Working Group regarding any additional steps necessary for scheduling or potential WG assignment, if appropriate.

Charter / Scope Summary:

- Problem Statement:
Scientific and enterprise data workflows often require unified, low-latency, structured data access across distributed systems. Current solutions either incur high serialization overhead or lack native support for data stream transport, as well as multi-hop auditing of data access.

- Scope:
Define a Streaming DataFrame (SDF) model and a protocol (DACP) for structured, streaming, cross-node, and cross-process data access leveraging Arrow Flight. Includes data model, operations, framing strategy, and basic security considerations.

- Goals:
1. Standardize a low-latency protocol for accessing both structured and unstructured data.
2. Support semantic data collaboration across heterogeneous systems.

- Non-Goals:
1. Not redefining or replacing application-layer features already covered by Arrow Flight. DACP builds on Arrow Flight transport.
2. Not defining a complete storage layer, database, or query language standard. DACP is not a database protocol.
3. Not handling authorization beyond relying on existing transport security mechanisms (e.g., TLS).
4. Not intended to replace general-purpose transfer protocols (e.g., FTP, HTTP, NFS, gRPC). DACP targets structured, streaming, cross-node data collaboration.

- Deliverables:
1. DACP protocol specification (Internet-Draft / RFC).
2. Reference implementation or pseudo-code for SDF streaming.
3. Example data models and use cases.

The full Internet-Draft can be found here:

Please let me know if any additional information or clarification is required for the scheduling process.

Thank you very much for your attention and assistance.

Best regards,
Xiaojie Zhu
