 ## Examples
 
+
+### Webpages
+
+For the webpage "https://myblog.example.com/post/2012-03-27/hello-world" the "i" and "k" tags are:
+
+```jsonc
+[
+  ["i", "https://myblog.example.com/post/2012-03-27/hello-world"],
+  ["k", "web"]
+]
+```
+
+### Books:
+
+- Book ISBN: `["i", "isbn:9780765382030"]` - https://isbnsearch.org/isbn/9780765382030
+
+Book ISBNs MUST be referenced _**without hyphens**_ as many book search APIs return the ISBNs without hyphens. Removing hypens from ISBNs is trivial, whereas adding the hyphens back in is non-trivial requiring a library.

+### Podcasts:
+
+- Podcast RSS Feed GUID: `["i", "podcast:guid:c90e609a-df1e-596a-bd5e-57bcc8aad6cc"]` - https://podcastindex.org/podcast/c90e609a-df1e-596a-bd5e-57bcc8aad6cc

+- Movie ISAN: `["i", "isan:0000-0000-401A-0000-7"]` - https://web.isan.org/public/en/isan/0000-0000-401A-0000-7
+
+Movie ISANs SHOULD be referenced  _**without the version part**_ as the versions / edits of movies are not relevant. More info on ISAN parts here -  https://support.isan.org/hc/en-us/articles/360002783131-Records-relations-and-hierarchies-in-the-ISAN-Registry

 ### Blockchain
 
 `<blockchain>` can be any layer 1 chain (`bitcoin`, `ethereum`, `solana`, ...). If necessary (e.g. for ethereum), you can specify a `<chainId>`.
