The Scandinavian Runic-text Data Base (Swedish: Samnordisk runtextdatabas) is a project involving the creation and maintenance of a database of runic inscriptions. The project's goal is to comprehensively catalog runestones in a machine-readable way for future research. The database is freely available  via the Internet with a client program, called Rundata, for Microsoft Windows and ASCII text files for other operating systems.
The origin of the Rundata project was a 1986 database of Swedish inscriptions at Uppsala University for use in the Scandinavian Languages Department. At a seminar in 1990 it was proposed to expand the database to cover all Nordic runic inscriptions, but funding for the project was not available until a grant was received in 1992 from the Axel och Margaret Ax:son Johnsons foundation. The project officially started on January 1, 1993 at Uppsala University. After 1997, the project was no longer funded and work continued on a voluntary basis outside of normal work-hours. In the current edition, published on December 3, 2008, there are over 6500 inscriptions in the database.
Work is currently underway for the next edition of the database.
Format of entries
Each entry includes the original text, its format, location, English and Swedish translations, information about the stone itself, et cetera. The stones are identified with a code which consists of up to three parts.
- Bo - Bohuslän
- D - Dalarna
- G - Gotland
- Gs - Gästrikland
- Hs - Hälsingland
- J - Jämtland
- Lp - Lappland
- M - Medelpad
- Nä - Närke
- Sm - Småland
- Sö - Södermanland
- U - Uppland
- Vg - Västergötland
- Vr - Värmland
- Vs - Västmanland
- Ög - Östergötland
- Öl - Öland
- BR - British Islands
- DR - Denmark (includes Skåne, Halland, Blekinge, and Southern Schleswig). Stone numbers taken from Jacobsen & Moltke Danmarks Runeindskrifter (1941-1942)
- FR - Faroe Islands
- GR - Greenland
- IR - Ireland
- IS - Iceland
- N - Norway
- X - Other areas
The second part of the code consists of a serial number or a previous method of cataloging.
- # - inscription lost, later replaced with †
- $ - newly retranslated
- M - inscription from the Middle Ages
- U - inscription in Proto-Norse, i.e. before ca 800.
- [inscription from the Viking Age, if M or U are not present]
As such, U 88 would mean that the stone is from Uppland and that it is the 88th to be catalogued. This system has its origin in the book Sveriges runinskrifter (English: "Runic Inscriptions of Sweden")
Dating of runic inscriptions in Rundata
Most of the time, the Period/Datering information in Rundata just gives the date as V, meaning Viking Age, which is very broad. For some Danish inscriptions from Jacobsen & Moltke a more precise sub-period is given. The periods used are:
- Helnæs-Gørlev — c. 800 (or 750 - c. 900)
- för-Jelling (pre-Jelling) — c. 900
- Jelling (Jelling) — 10th century and into the 11th century
- efter-Jelling (post-Jelling) — c. 1000 – 1050
- kristen efter-Jelling (Christian, post-Jelling) — 1st half of the 11th century
The date bands are:
- RAK — c. 990-1010 AD
- FP — c. 1010-1050 AD
- Pr1 — c. 1010-1040 AD
- Pr2 — c. 1020-1050 AD
- Pr3 — c. 1050 - a generation forward (en generation framåt)
- Pr4 — c. 1060-1100 AD
- Pr5 — c. 1100-1130 AD
