Improving Findability
Metadata, keywords, and tags are essential components that significantly improve the findability of open data.
Metadata
High-quality metadata is crucial for several reasons:
Contextual Information: Metadata provides context about the data, such as its creator, creation date, format, and purpose. This context helps users understand the relevance and applicability of the data.
Standardisation: Using standardized metadata schemas (e.g., Dublin Core, DCAT) ensures that metadata is consistent and interoperable across different platforms and systems.
Search Engine Indexing: Search engines use metadata to index and rank content. Well-structured metadata improves the chances that your data will appear in search results.
Filtering and Sorting: Metadata enables users to filter and sort data based on various criteria, making it easier to find specific datasets within large repositories.
Keywords
Keywords are specific terms that describe the main topics or themes of the data. They play a critical role in improving findability:
Relevance: Keywords help users quickly determine the relevance of a dataset. By including relevant keywords, you increase the likelihood that your data will be discovered by users searching for specific topics.
Search Engine Optimization (SEO): Keywords are a fundamental aspect of SEO. Including relevant keywords in your metadata and data descriptions can improve your data's ranking in search engine results.
User Queries: Keywords align with the terms users are likely to enter into search engines or data portals. By anticipating and including these terms, you make your data more discoverable.
Tags
Tags are similar to keywords but are often more flexible and user-generated. They can be added by both data providers and users to categorize and describe data:
Flexibility: Tags allow for a more dynamic and community-driven approach to categorization. Users can add tags that reflect their own understanding and use of the data.
Crowdsourcing: Tags can be crowdsourced, enabling a broader range of perspectives and increasing the likelihood that the data will be found by diverse users.
Faceted Search: Tags support faceted search, allowing users to filter and refine their searches based on multiple criteria. This makes it easier to find specific datasets within large collections.
Best Practices for Metadata, Keywords, and Tags
Consistency: Use consistent terminology and follow established standards for metadata, keywords, and tags.
Relevance: Ensure that keywords and tags are relevant to the content of the data. Avoid using generic or overly broad terms.
Comprehensiveness: Provide comprehensive metadata that includes all essential details about the data. Include a variety of keywords and tags to cover different aspects of the data.
User-Friendly: Make metadata, keywords, and tags user-friendly and easy to understand. Avoid jargon unless it is necessary and well-defined.
Updates: Regularly update metadata, keywords, and tags to reflect changes in the data or new insights from users.
AI Update: If you only have a few (or no) user queries to guide you, try asking conversational generative AI such as ChatGPT to suggest more. A good prompting strategy here is to use a 'persona', such as, 'I'm interested in finding data on water quality. What are some of the key terms I might use in a Google Search?'
AI Update: Frequently, keywords in metadata are missing or inconsistent. ChatGPT and other generative AIs can be used to suggest more.
