Handle System vs DOI vs URL vs URI (LIS Perspective)

Handle System vs DOI vs URL vs URI (LIS Perspective)

Keywords: Handle System, DOI, URL, URI, Persistent Identifier, Link Rot, DSpace, Digital Libraries, Metadata, LIS NET

🔍 1. Basic Idea

  • Handle: Persistent identifier for digital objects
  • DOI: Standardized persistent identifier (built on Handle)
  • URL: Location of resource
  • URI: General identifier

🧩 2. Detailed Comparison

Feature Handle System DOI URL URI
Nature Persistent Identifier Standardized Persistent Identifier Locator (Address) General Identifier Concept
Purpose Ensures long-term access Used for scholarly publishing & citation Specifies web location of a resource Identifies any type of resource
Stability Stable Highly Stable Unstable (can break) Depends on type
Managed by Corporation for National Research Initiatives (CNRI) International DOI Foundation (IDF) Web servers / hosting systems Defined by web standards (IETF)
Use in LIS Institutional repositories (e.g., DSpace) Research articles, journals, datasets Web pages, digital documents Metadata schemas & semantic web
Example hdl.handle.net/1234/567 doi.org/10.1000/xyz123 https://example.com/file.pdf URI can be URL or URN

📌 3. Key Differences

Handle vs DOI: DOI is built on Handle and widely used in publishing.

Handle vs URL: Handle is permanent; URL may break.

DOI vs URL: DOI redirects to current location.

URI vs URL: URL is a type of URI.

🔁 DOI Resolves to Current URL

DOI acts as a permanent pointer that redirects to the updated location.

🧠 Analogy

  • URL → Address
  • Handle → Aadhaar
  • DOI → Passport
  • URI → Any identifier

⚠️ NET Exam Traps

  • DOI = Handle application
  • URL is not persistent
  • URI includes URL + URN
  • Handle used in repositories
