Study Notes

Web3

Tim Berners-Lee envisioned Web 3.0 as a semantic web enabling shared and reusable linked data across various platforms.
Focuses on technology-driven meaning construction and task completion, rather than human interpretation.
Coined in 2014 by Gavin Wood, Web3 refers to a decentralized internet powered by blockchain technology.
Elon Musk questioned the reality of Web3, labeling it as more of a marketing term than a tangible concept.
Berners-Lee disagrees with blockchain-based Web3, stressing user control over personal data through features like:
- Global single sign-on for universal access.
- Login IDs for data sharing among users.
- A universal API for data retrieval across platforms.
Transition from Web 2.0 to Web 3.0 is ongoing, with key differences noted:
- Centralization vs. decentralization.
- Traditional currency vs. cryptocurrencies.
- Use of cookies vs. NFTs.
- Web applications vs. smart applications utilizing AI and machine learning.

Metaverse

The metaverse is envisioned as a shared, immersive 3D virtual space enhancing online human experiences.
Comprised of seven layers addressing technology to user experience:
- Layer 1: Infrastructure.
- Layer 2: Data management via mobile records.
- Layer 3: Blockchain for decentralized transactions.
- Edge computing improves data processing and responsiveness.
- Layer 4: Spatial computing using Extended Reality (XR).
- Layers 5-7: Focus on commerce, discovery, and user experience.

Extended Reality (XR)

XR encompasses Augmented Reality (AR), Virtual Reality (VR), Mixed Reality, and upcoming technologies.

Augmented Reality (AR)

AR integrates real-world and digital content, enhancing user experience rather than replacing it.
Pokémon Go is a noted AR example, driving foot traffic to businesses.
AR applications span various fields, including:
- Design and construction for product visualization.
- Manufacturing for remote maintenance assistance.
- Healthcare for surgical guidance.
Edge computing combined with AR enhances access to real-time data and user engagement.

Virtual Reality (VR)

Describes a fully immersive, three-dimensional digital environment for exploration and interaction.
Saw increased interest during the COVID-19 pandemic as an alternative meeting platform.
Platforms like Virbela offer virtual spaces for meetings with engaging avatar interactions.

Mixed Reality

Combines real and digital worlds that interact in real-time, requiring more processing power and specific headsets like Microsoft's HoloLens.

Digital Twins

A digital twin is a virtual model representing a physical object or system with updates via real-time data.
Differentiates from simulations by using continuous updates versus predefined datasets.
Widely employed in manufacturing and engineering to monitor and optimize performance.

Records Management in the Metaverse

Records and Information Management (RIM) faces new challenges in capturing content within the metaverse.
Organizations should incorporate metaverse-related information into records retention schedules and governance plans.
The metaverse economy could contribute $3 trillion globally by 2031, emphasizing the need for thorough record management of digital assets and user interactions.
Examples of records in a virtual art gallery include store layout and design, digital assets (NFTs), and transaction data regarding user behavior and purchases.
