Digital curation is the selection, preservation, maintenance, collection and archiving of digital assets.

Digital curation is the process of establishing and developing long term repositories of digital assets for current and future reference by researchers, scientists, and historians, and scholars generally.

Digital curation entails:

• Collecting verifiable digital assets
• Providing digital asset search and retrieval
• Certification of the trustworthiness and integrity of the collection content
• Semantic and ontological continuity and comparability of the collection content

Significant and major challenges faced by digital curation are:

• Storage format evolution and obsolescence
• Rate of creation of new data and data sets
• Broad access and searching flexibility and variety
• Comparability of semantic and ontological definitions of data sets

The challenges faced by digital curation are resulting in:

• specialised research institutions
• academic courses
• dedicated symposia
• peer reviewed technical and industry journals

to address the challenges.
