2. COVID and “post-COVID”
• Postponed archaeological fieldwork activities
• Archaeological work:
– on the field and
– in front of the laptop – preferably everything in
digital format

3. ARCHAEOLOGICAL INFORMATION SYSTEM
ARCHAEOLOGICAL MAP OF BULGARIA
(AIS AKB)

4. Data Collections
• AIS AKB:
– Developed for the needs of archaeologists for
regional data in Bulgaria
– “Site and monuments” information system
– Legacy data
– Controlled vocabulary
– Daily/weekly/monthly updated

5. NIAM-BAS, AIS AKB, A+
1. Title and Scope: AIS AKB, Bulgaria, recorded
archaeological sites
2. 4.4.0.1 - Sites and monuments inventory records
i.e. databases of archaeological sites
3. Geographical range – Bulgaria
4. Chronological range –
from Paleolithic to Renaissance
5. Limited access: https://www.lex.bg/laws/ldoc/2135726967

6. NIAM-BAS, AIS AKB, A+
• 3 .xml files mapped to AO-Cat :
– For the information system
– For the sites present in ARIADNE
– For the burial mounds
• Mapping of site types, findings and facilities to AAT Getty
vocabulary (http://www.getty.edu/research/tools/vocabularies/aat/), using
Simple Knowledge Organization System (SKOS)
(https://www.w3.org/2004/02/skos/)
• Chronologies – in PeriodO (http://perio.do/)

7. 3M mapping tool
• Two sets of mapping:
– For a collection (the information system)
– For an individual data source (the sites
themselves)

8. AIS AKB in ARIADNE portal

9. ARIADNE portal
• Around 1000 number of records

10. ARIADNE portal
• Around 1000 number of records

11. ARIADNE portal
• Around 1000 number of records

12. 2021
• Burial mounds and mound necropolises

13. The relevance
Archaeological Information
System “Archaeological Map
of Bulgaria”
– Dataset publication and
availability at international
level
– Mapping to international
thesaurus
– English translation
– Geographic coordinates of
archaeological sites
– Training of young scientists in
importance of data
standardization
Overcoming
incomplete-
ness and
isolation
Mapping
Spatial
location

14. Rescue fieldwork activities
– Transport and
gas pipeline
infrastructure
projects;
– Concession
