# Situation Analysis
I recently stumbled upon an Email message from The Information comprising an anlysis of Identity Authenticity products, offers, and prices across key Social-Media service providers. Naturally, I would like to save this information to a Knowledge Graph for future reuse and recall that satisfies the following conditions:

1. Original source is cited
1. Pricing & Offers needs to be pegged to actual service providers i.e., implicit attribution using hyperlinks
1. Machine-computable and easily referenced, courtesy of RDF deployed using Linked Data principles

## How do I achieve that?

Here's a CHAT-GPT transcript that offers the solution while also showcasing why it is such a complimentary tool regarding the notion of a Semantic Web.

Q: Using a code-block for output, generate entity descriptions using RDF-Turtle from the data table that follows, using the following guidelines

1. Use terms from Schema.org
1. Denote subjects and objects using hash-based hyperlinks 
1. Use the value from the Home Page column to the @base value for each Product description
1. Place `## Turtle Start ##` and `## Turtle End ##` around the code within the code-block
1. Describe the first three product, product features, and associated offer combinations
1. Derive product features from the Features column
1. Associate each product description with https://www.theinformation.com/articles/how-meta-verified-compares-to-other-social-subscriptions using a schema:relatedLink attribute
