Sigmod submission

SIGMOD Submission

Run this audit before a round deadline. SIGMOD research papers are journal submissions to PACMMOD (Proceedings of the ACM on Management of Data), reviewed in year-round batches rather than one annual cutoff, so the first question is always "which round," not "which year." Reopen the live CFP for the cycle you target before trusting any number quoted here.

What must be true a week early

SIGMOD front-loads part of the deadline: the abstract and the declaration of conflicts of interest are due roughly one week before the paper itself (SIGMOD 2027: the 10th vs. the 17th of the round month, 11:59 PM AoE). Missing the abstract stage closes the round entirely — there is no PDF-only entry.

• Register the submission in Microsoft CMT with final title, abstract, topic areas, and the complete author list.
• Declare COIs honestly and completely; PC assignment happens off this data.
• Count your load: SIGMOD 2027 caps each author at ten research-track submissions across all four rounds combined.
• Decide now whether a weak draft should wait a round; a rejection triggers a 12-month embargo, and a late withdrawal is treated as a rejection too.

Format and anonymity gate

Check	SIGMOD 2027 rule (verify per cycle)	Failure mode
Length	12 pages max, unlimited pages for references	Desk reject
Template	Current ACM template, fonts/margins untouched	Desk reject
PACMMOD format	Only for final publication, never for submission	Confused reviewers, chair flag
Author identity	No names, affiliations, or funding acknowledgements	Desk reject
Colleague thanks	No research-group or collaborator acknowledgements	Anonymity violation
Self-references	Third person, no "our prior system" giveaways	Reviewer discount or flag
Artifacts	Links must not expose authorship or institution	Anonymity violation

Note the asymmetry with one-shot conferences: because reviewing is double-anonymous across the full round — including any revision phase — the anonymity discipline must survive months, not weeks. Plan artifact hosting accordingly.

Exclusivity and overlap

PACMMOD requires substantial novel content and exclusive consideration: once submitted, the paper (or anything with substantial overlap in results) stays out of every other venue until PACMMOD rejects it or you withdraw. Rolling PVLDB submissions of a sibling paper are the classic accidental violation — map the overlap between your group's pipelines before the abstract stage.

Round-selection judgment

• Submit to the earliest round the evidence genuinely supports; a revision verdict already builds in one more month of runway.
• Do not burn a round on a draft whose experiments are still moving — the embargo prices failure at three skipped rounds, not one.
• If a companion paper is in PVLDB's monthly queue, stagger topics so neither submission poisons the other's novelty claim.
• Check whether the industrial track fits better before defaulting to research; its calendar and rules are separate and single-shot.

Ten-day countdown

D-10  Freeze contribution claims; stop adding experiments
D-9   Abstract, author list, topics, and COIs into CMT
D-7   Anonymity sweep: PDF metadata, repo URLs, funding lines, cluster names
D-5   Rebuild every plot from committed scripts; diff against paper numbers
D-3   Full ACM-template compliance pass; reference pages excluded from count
D-2   Fresh-eyes read of pages 1-2 by someone outside the project
D-1   Upload final PDF; confirm CMT shows the intended file version
D-0   Re-download from CMT and open the PDF you actually submitted

All cutoffs 11:59 PM AoE. Source: https://2027.sigmod.org/calls_papers_important_dates.shtml. Future cycles will shift these dates; treat the pattern (quarterly rounds, abstract a week early) as the durable part and the dates as perishable.

Common desk-reject and triage patterns

• Page 13 of content because an appendix crept ahead of the references.
• A GitHub link whose organization name is the authors' lab.
• Abstract registered under a placeholder title that never got updated.
• The same experimental core simultaneously sitting in a PVLDB revision.
• An acknowledgements section pasted in from a camera-ready of prior work.

None of these are recoverable after the round deadline; all of them are findable in an afternoon before it.

PODS co-location caution

SIGMOD ships with PODS, the theory symposium, under one registration and one week — but they are separate venues with separate CFPs, PCs, deadlines, and publication series. Concretely:

• A theory-leaning paper does not "fall through" to PODS if SIGMOD rejects it; it must be submitted to PODS on PODS's own calendar.
• Do not cite SIGMOD round dates when planning a PODS submission, and vice versa; the calendars are unrelated.
• The exclusivity rule still applies across the pair — the same results cannot sit in both queues at once.

Final self-audit, one minute each

• Open the uploaded PDF from CMT and read the title, author-block area, and page count with fresh eyes.
• Search the PDF text for your surnames, institution, and grant numbers.
• Click every URL in the paper from an incognito window.
• Confirm the abstract in CMT matches the PDF abstract verbatim.
• Confirm the round you think you entered is the round CMT shows.

Output format

[Round verdict] submit this round / hold one round / reroute track
[CMT gate] abstract+COI status, author cap headroom
[Format gate] pages / template / reference handling
[Anonymity gate] pass or the specific leak found
[Overlap gate] PVLDB or other-venue conflicts, embargo exposure
[Ordered fixes] <what to repair before the abstract stage>
