The Process

• This year, a program committee for demo papers was introduced.

• All submissions were reviewed by (at least) three reviewers.

• All deadlines were met – notification was even given early!

The Process

• A PC chair meeting was held in Seattle.• Prior to this, the PC members had discussed the papers

they had reviewed.• The final selection of papers to accept was made at the

PC chair meeting.

• Rigorous conflict of interest mechanisms were enforced.

• No quota on the number of papers that could be accepted was enforced.

Decoupling of the number of presentation slots and acceptance. In the future, the lengths of presentation slots may vary. We need kinder reviewing to obtain higher acceptance rates.

Observations

• Workshops VLDB 1995 had one. This year, we have the largest workshop program ever. Should some workshops occur in parallel with the conference?

• Submission procedure About 30% of the abstract submissions never materialize. Of little value to have two deadlines?

• Proceedings They are beautiful, inside and out. They could be the last hardcopy VLDB proceedings. A very limited edition – very few exist. They are true collector’s items. Who gets to the registration desk first? PS. Bring money.

Acknowledgments
