FAIRsharing record for: Dateno

This FAIRsharing record describes: Dateno is a next-generation dataset search engine that provides fast, comprehensive access to open datasets worldwide. Our mission is to make data discovery and integration as seamless as possible for researchers, analysts, developers, journalists, and anyone else working with data.

Our Vision

We believe that access to data should be easy and efficient. By creating a powerful search engine specifically for datasets, we aim to accelerate research, innovation, and data-driven decision-making across various fields.
What Sets Us Apart

Speed: We've optimized our search functionality to deliver results as quickly as possible using Meilisearch.
Comprehensive Filtering: Our advanced filtering system allows users to narrow down results by various parameters, making it easier to find exactly what you need.
API-First Architecture: We're building Dateno with API access in mind, allowing for seamless integration into your workflows and applications.
Extensive Index: Our constantly growing index includes millions of records from thousands of data catalogs worldwide.
Data Preservation: We're committed to archiving datasets that are at risk of disappearing, ensuring valuable data remains accessible.

How It Works
Dateno is built on the Dateno registry of data catalogs. We crawl various types of data sources, including:

- Open data portals
- Geoservers/geoportals
- Scientific data repositories
- Microdata catalogs
- Databases of indicators

We use common APIs and export formats like DCAT, CKAN API, CSW, WFS, WMS, and ArcGIS Rest API to gather data. After crawling, we enrich the data and convert it to a unified structure similar to DCAT, creating a single search index.

本FAIRsharing记录介绍的是：Dateno是一款下一代数据集搜索引擎，可快速、全面地获取全球范围内的开放数据集。我们的使命是为研究人员、分析师、开发者、记者以及所有从事数据相关工作的人员，打造尽可能流畅无缝的数据发现与集成体验。

我们的愿景
我们坚信数据获取应当便捷高效。通过打造专为数据集设计的高性能搜索引擎，我们致力于加速各领域的研究、创新与数据驱动型决策进程。

核心优势
- 极速检索：我们基于Meilisearch优化了搜索功能，可极速返回检索结果。
- 全面筛选：我们的高级筛选系统支持用户通过多维度参数缩小检索范围，便于精准匹配所需数据。
- API优先架构：我们采用API优先的架构开发Dateno，可无缝集成至各类工作流与应用程序中。
- 海量索引库：我们的索引库持续扩容，目前收录了来自全球数千个数据目录的数百万条数据记录。
- 数据留存保护：我们致力于归档濒临消失的数据集，确保有价值的数据始终可被访问。

工作原理
Dateno基于自身的数据目录注册表构建。我们会爬取多种类型的数据源，包括：
- 开放数据门户
- 地理服务器/地理门户（Geoservers/geoportals）
- 科学数据仓储
- 微数据目录
- 指标数据库

我们采用通用API与导出格式采集数据，包括DCAT（数据目录词汇表，Data Catalog Vocabulary）、CKAN应用程序编程接口（CKAN API）、CSW（目录服务Web，Catalogue Service for the Web）、WFS（要素服务Web，Web Feature Service）、WMS（地图服务Web，Web Map Service）以及ArcGIS Rest应用程序编程接口（ArcGIS Rest API）。爬取完成后，我们会对数据进行丰富完善，并将其转换为类似DCAT的统一结构，进而构建单一的全局检索索引库。
