Re: Buzzbang crawler and search release 0.0.2 now available

I used ShEx in the past but that was before SHACL. I do like the intuitive concise notation.

However my postdoc has been looking at both and finding the SHACL examples more accessible. Also the SHACL framework seemed more up to date.

For most purposes there probably isn't much in it. It would be good to know what are the things that can be done in one and not the other.

I also have a preference for ShEx. The syntax feels more intuitive. However, just recently a book describing and comparing both ShEx and Shacl was released: http://www.morganclaypoolpublishers.com/catalog_Orig/product_info.php?products_id=1091

Personally, I I like the regex style of expressing cardinalities and the possibility to combine different shapes for similar concepts in Shex.

I have a slight preference for Shex personally but the most official in W3C terms is Shacl.  Anyone else have a view?

[https://mail.google..com/mail/u/0/images/cleardot.gif]Thanks Dan.  Yes, I need to look into SHACL/SHEX - I only have a passing acquaintance with them at the moment.  Would you recommend either one over the other?

Regards,

This sounds great! It would be interesting to try to write down the specific data patterns you're extracting, by using W3C SHACL or SHEX shape markup. I will be attempting the same for Google...

Hi all,

Following on from the Bioschemas adoption meeting, I'm continuing to work on the extremely alpha Buzzbang Bioschemas crawler and frontend when I can (renamed from BsBang, after Alistair pointed out the connotations of 'bs' :)).

You can play with the current search engine by going to http://buzzbang.science

In this release, I decided to concentrate on indexing DataCatalog (this is extremely primitive as of yet, only recording the name, url, description and keywords properties).  If you go to buzzbang.science and search for terms such as 'data' or 'registry' you'll get some results.

Currently, I'm manually adding URLs - you can see the small list at [1]. I added those that have DataCatalog JSON+LD embedded that I had in my notes, such as identifiers.org<http://identifiers.org> and fairsharing.org<http://fairsharing.org>. Down the road, users will be able to submit URLs for crawling directly on the website, but for now, please contact me, raise a Github issue [2] or submit a pull request if there's an URL I can add.

Next, I plan to crawl the rest of DataCatalog, esp. embedded DataSets and think about how that information can help improve simple search.

All feature suggestions or pull requests welcome on the Github crawler [2] and search frontend [3] projects.
