The document summarizes the ARIADNE Portal project, which aims to create a common research portal for European archaeologists. Key points: - Funded EU infrastructure project with 24 partners across 16 countries and a budget of 6 million Euro - Will develop common standards, policies, and tools like a portal for accessing archaeological research data and documents from across Europe - Faces challenges like lack of existing common infrastructure/standards and varying technological expertise among partners - Will aggregate data from different sources using common metadata schemas and enrich data using thesauri and mappings before publishing on the portal

7. Elastic Stack

8. elasticsearch
• Json document based
• Built in replication for multiple nodes (if needed)
• Uses lucene index
• Handles many specialized fieldtypes eg. dates, numbers,
geoshapes etc
• REST based API
• Official clients in Java, Groovy, python, .net, Perl, Ruby and
PHP

13. Mappings
• Mappings not needed, elastic will ”guess” the field type ad
create a mapping
• Mappings are need for creating filters and buckets

14. Some Examples
• Live demo!
