Governance Structure
Administrative Framework
The eDataIndia portal is administered by the National Data Management Agency (NDMA), a statutory body established under the e‑Governance Act of 2015. NDMA operates under the oversight of the Ministry of Electronics and Information Technology, which sets policy directions and allocates budgetary resources. The agency is responsible for maintaining the technical infrastructure, ensuring data quality, and enforcing compliance with open data standards.
Data Stewardship
Data stewardship is divided among sectoral data stewards - appointed representatives from each participating ministry. These stewards are accountable for the integrity, accuracy, and timeliness of their respective datasets. They collaborate with NDMA’s data curation teams to apply standard formats, resolve metadata gaps, and publish updates. A cross‑functional Data Governance Council convenes quarterly to review policies, resolve disputes, and chart long‑term strategic goals.
Data Catalog and Standards
Dataset Coverage
eDataIndia hosts more than 3,000 datasets across 30 major sectors. Core areas include:
- Population and census data
- Agriculture production statistics
- Health facility and disease surveillance data
- Environmental monitoring indicators
- Education enrollment and performance metrics
- Transport and logistics statistics
- Energy consumption and generation records
- Economic indicators such as GDP, inflation, and trade balances
Each dataset is accompanied by descriptive metadata - title, source, temporal coverage, geographic granularity, data format, and licensing information.
Metadata Standards
eDataIndia adopts the ISO 19115 standard for geographic information and the ISO 19139 XML schema for metadata exchange. For non‑spatial datasets, the DataCite metadata schema is used to facilitate discoverability and citation. All metadata fields are mandated to include a unique identifier, facilitating data reuse and interlinking across the portal.
Data Formats and Licensing
Datasets are made available primarily in CSV, JSON, XML, and Excel formats. Binary and image data are stored in TIFF and PNG formats where applicable. All datasets are released under the Open Government Licence – India (OGL‑I), allowing free redistribution, modification, and commercial use provided that the source is cited.
Technical Infrastructure
Platform Architecture
The eDataIndia portal is built on a microservices architecture hosted on a hybrid cloud environment. Core services include:
- Data ingestion microservice that pulls data from source systems via secure APIs.
- Metadata catalog service that aggregates descriptive information.
- Search and discovery service powered by Elasticsearch.
- API gateway that exposes RESTful endpoints for dataset retrieval.
- Authentication service employing OAuth 2.0 for user and application access control.
Data storage utilizes a combination of object storage for raw files and relational databases for structured metadata. A dedicated CDN ensures fast global delivery of public datasets.
Security and Compliance
Security is enforced at multiple layers. All data transfers occur over TLS 1.2+. API endpoints require bearer tokens and are monitored for anomalous traffic. The platform is compliant with the Indian IT Act, 2000, and follows the Data Protection Principles of the Personal Data Protection Bill, 2019. Periodic penetration testing and vulnerability assessments are conducted by external auditors.
Scalability and Performance
Horizontal scaling of microservices is managed by Kubernetes clusters. Auto‑scaling rules adjust compute resources based on API request load, ensuring low latency during peak usage. Data caching layers employ Redis for frequently accessed datasets, reducing database query overhead.
