======  publictimestamp.org ======
=====  Implementation =====

The website will be pure XSLT, that transforms the server's XML-Answers to HTML.

The server will also provide special //xsltpassthrough// parameters, making it easyer for the xslt to maintain it's current state.
=====  Possible Web-Interface =====

//suggestion by Jan//
====  search ====

To find some special timestamp for verification, there are several methods to do so:

{{https://wiki.linuxfoundation.org/images/1/17/Search_by_metainfo.png?nolink|}}

After clicking search, you'll get as answer the [[https://www.linuxfoundation.org/collaborate/workgroups/osapa/pt_web-site#search_results|search result]]

{{https://wiki.linuxfoundation.org/images/5/55/Search_by_hash_or_id.png?nolink|}}
====  search results ====

The search results are all displayed including a link to the [[https://www.linuxfoundation.org/collaborate/workgroups/osapa/pt_web-site#timestamp_details|timestamp details]]

{{https://wiki.linuxfoundation.org/images/0/0c/Search_result.png?nolink|}}
====  timestamp details ====

The detailed view of a timestamp has a link to the accoring [[https://www.linuxfoundation.org/collaborate/workgroups/osapa/pt_web-site#ptb_-_public_timestamp_block|PTB]].

{{https://wiki.linuxfoundation.org/images/b/bd/Timestamp-for-single-file.png?nolink|}}

Of course the timestamp-details also display the meta-information of the timestamped file again. This looks the same as I already showed in the [[https://www.linuxfoundation.org/collaborate/workgroups/osapa/pt_web-site#search_results|search result]]
====  PTB - Public Timestamp Block ====

The PTB (Public Timestamp Block) details page contains all information neccessary to verify the Timestamps yourself.

  *  A link to the hash-values of this block (looks like [[https://www.linuxfoundation.org/collaborate/workgroups/osapa/pt_web-site#latest_ptb_for_new_publications|this]])
  *  A link to all the 'timestamp details pages' of files that were timestamped within this block (looks like [[https://www.linuxfoundation.org/collaborate/workgroups/osapa/pt_web-site#search_results|this]])
  *  A list of all known publications of the hash values of this specific PTB
  *  Follow-up blocks, which contain (as described by [[https://www.linuxfoundation.org/collaborate/workgroups/osapa/timestamping_introduction#endless_logfile|Endless logfile]]) the Hash of this PTB as a whole.
  *  //photos// is just an idea we can discuss, but for explanation it could be helpful if we provide photos of the magazine's page that containes the hash-values (if they send us one of course only).
  *  A download link to download this block to self-verify it

{{https://wiki.linuxfoundation.org/images/f/f0/Block2.png?nolink|}}

How are these blocks connected? Read [[https://www.linuxfoundation.org/collaborate/workgroups/osapa/timestamping_introduction#endless_logfile| Timestamping_Introduction#Endless_Logfile ]].
====  latest PTB for new publications ====

This here shows what everybody would need to publish. (Of course not exactly this, but always the latest version :)

Of course we could make this a little smaller, and maybe provide different versions. For example we could skip the non-cryptographic hash-values (as all the smaller checksums) for magazines. Those are mostly here for easyer searching and verification. The evidence comes from the big ones :)

{{https://wiki.linuxfoundation.org/images/d/d0/Block_publication2.png?nolink|}}
====  public access to PTBs ====

PTBs must all be public available for download!

  *  Its very important that this data won't get lost or corrupted
  *  For more security everybody should be able to mirror these files, and we should even encourage others to do so
  *  For verification of timestamps everybody must be able to download these files (of course only single ones, to find the right one above search mechanism gets implemented)
