Summary
Nummi Digitali is a new multimodal platform for studying and sharing numismatic heritage. It integrates coin data, 3D models, and chemical analysis, creating a unified digital resource for researchers and the public.
Area of Science:
- Digital Humanities
- Archaeometry
- Numismatics
Background:
- Traditional numismatic studies often lack integrated digital tools for diverse data types.
- Disseminating numismatic heritage requires standardized, interoperable digital platforms.
Purpose of the Study:
- To introduce Nummi Digitali, a novel multimodal platform for the comprehensive study and dissemination of numismatic heritage.
- To establish a unified digital infrastructure connecting traditional numismatic data with advanced analytical information.
Main Methods:
- Development of a web-based platform adhering to Italian ministerial standards, international interoperability protocols, and Linked Open Data (LOD) principles.
- Integration of high-resolution 2D imaging, 3D metric models, and archaeometric data (including XRF analysis).
- Implementation of a tiered user interface for both specialist analytical tools and public-accessible visualization.
Main Results:
- Successful testing on a core collection of Greek, Punic, and Roman coins from the "A. Salinas" Regional Archaeological Museum.
- Demonstrated significant outcomes in scientific analysis, historical contextualization, and public engagement.
- Established a new paradigm in digital numismatics by unifying diverse data types.
Conclusions:
- Nummi Digitali offers a scalable, standards-compliant model for interdisciplinary research in digital cultural heritage.
- The platform represents a transformative approach to cataloging, studying, and disseminating numismatic collections.
- It enhances both scientific inquiry and public accessibility to numismatic heritage.

Since the early 2000s, computer-mediated communication (CMC) has grown rapidly, playing a crucial role in self-development. A key distinction between CMC and real-life interactions is the lack of a physically present partner. This absence makes non-verbal cues such as facial expressions, body language, and paralinguistic signals unavailable in CMC platforms like email, instant messaging, or social media. The lack of these cues can create ambiguity and complicate how feedback is interpreted.The...

Some researchers gain access to large amounts of data without interacting with a single research participant. Instead, they use existing records to answer various research questions. This type of research approach is known as archival research. Archival research relies on looking at past records or data sets to look for interesting patterns or relationships. For example, a researcher might access the academic records of all individuals who enrolled in college within the past ten years and...
