By way of Egyptology News, we learn of a forthcoming release from Ilona Regulski and the Institut für Ägyptologie und Koptologie der Westfälischen Wilhelms-Universität Münster:
The current database (which will be accessible to the general public soon) assembles all available Early Dynastic inscriptions, covering the first attestations of writing discovered in tomb U-j (Naqada IIIA1, ca. 3250 BC) until the earliest known continuous written text in the reign of Netjerikhet–more commonly known as Djoser (ca. 2700 BC). The database contains 4524 inscriptions [and] includes detailed information regarding date, provenance, type of inscription, dating criterion, and present depository.
The conversion of the database from Microsoft Access to a more web-friendly form (presumably PHP over MySQL as other databases from the same department) is reportedly in final stages under the care of Erhart Graefe at Münster. We will watch the Database of Early Dynastic Inscriptions Login Page for the promised public unveiling (it is presently password-protected).
