SymRe is a short URL service similar to tinyURL or bitly.
All URLs are stored on the Bitcoin (BSV) network and are accessable to anyone.
Other URL shortener services have existed for many years and are free to use.
The issue with traditional services is that the database is only accessable to the service provider.
Which means should the service provider stop to provide its serice we would lose all access to the short URLs
Because SymRe stores the short URLs on Bitcoin not only will they never be deleted they are also accessable for other service providers other then SymRe itself.

We can use the piping schema described by unwriters bitcom protocol to add metadata.
SymRe currently uses MAP and HAIP for metadata and signing.
Here is an example of SymRe with additional metadata stored using MAP:
OP_0 OP_RETURN 1SymRe7erxM46GByucUWnB9fEEMgo7spd [URL] | 1PuQa7K62MiKCtssSLKy1kh56WWU7MtUR5 SET app symre title [title] description [description] category [category] tags [tags]
Here is an example of using HAIP to sign the data:
OP_0 OP_RETURN 1SymRe7erxM46GByucUWnB9fEEMgo7spd [URL] | 1PuQa7K62MiKCtssSLKy1kh56WWU7MtUR5 SET app symre title [title] description [description] category [category] tags [tags] | 1HA1P2exomAwCUycZHr8WeyFoy5vuQASE3 SHA256 BITCOIN_ECDSA [persona/bitcoin address] [signature] 0x00
