@GuillaumeRossolini
You are indirectly talking about the need for long-duration energy storage #LDES, and especially seasonal energy storage. Saving up energy to last for the average 14-day Dunkelflaute is important in all locales. And yes, seasonal storage for getting through the winter is also very important. And yes, most analysts agree that for 2+ weeks of LDES, including seasonal storage, hydrogen is the lowest cost storage vector. -

Next week we’re hosting the second in-person #LDES workshop at #SEMIC2025.
Piotr Sowiński will be the keynote speaker. He developed Jelly, a binary RDF format for syncing RDF datasets at speeds we can only aspire to.
What is his opinion about the work we’re doing? What can we learn from eachother? Looking forward to the talk and the discussion!

@pietercolpaert Is there a document that compares #LDES with related methods of synchronization such as Revsion Control Systems, OAI-PMH, ResourceSync? It looks like the problem to be solved is a variant of the Cache Invalidation in "Only two hard problems in Computer Science".

After 4 years of this blog post being in draft, I’ve just published the initial motivation for working on Linked Data Event Streams #LDES and kept the date at which it was planned to appear: https://pietercolpaert.be/ldes/2021/09/03/ldes
It elaborates on the maintenance hell for APIs and replication hell with dumps, and how we are fighting this status quo with the #SEMIC LDES initiative.

My #SolidProject client and server are now ready for efficient access control demos on #BigData using the HTTP WG's 's "Signing HTTP Messages".
I can demo with a server publishing N resources (in this case, #LinkedData Event Stream (#LDES) data.
The client is implemented in #Scala using #http4s, and the server uses #Akka.
The libraries can be compiled to JS for use on #nodeJS frameworks too. Native is not far off, either.
The client need make no more than N+2 requests:1. Request 1 on a resource R returning a "401 Unauthorised"
2. a max of 2 requests to get the access control rules
3. from there on, N signed requests using #HttpSignatures (when those all fall in the same container space)Solid clients are essentially like Search Engine crawlers fetching data on the web, so they need to jump around from website to website. Having approx 2 requests extra per website for auth is very interesting in that scenario.
Note: those 2 requests can be cached, so those may be only needed once over a long period of time. The connection efficiency is possible by combining the following pieces:
• using the IETF's HTTPSig (a version from the beginning of the year)
• using default rules (part of the spec)
• caching of ACLs on the client
• the use of a "defaultAccessContainer" link header to reduce the number of requests.I am trying to work out who may be interested in such a technical demo, what a good time for it may be, ...

@nichtich I'm glad if I receive that for consumption.
For publishing the higher cost seems to come from ensuring we have the data with sufficient quality. Offering different formats is relatively cheap. We do #sparql and #turtle by default for most of the data, depending on where it's shared. #LDES is coming soon for most of those. Adding #HDT could be nice over time.
More adoption is more fun.
