Freebase Reference Field Module

Based on the comments in http://groups.drupal.org/node/152939 I made a draft implementation of what I was considering as a 'semantic form widget' using Freebase's 'suggest' widget.

Module code is available here: http://github.com/adorsk-whoi/fb_reference

Details

The module defines a 'Freebase Reference' field type which can be used to reference freebase topics via Freebase's suggest widget.

Semantic Forms in Drupal: Making the Semantic Web Usable

Are there any current initiatives for semantic forms in Drupal?

A more detailed explanation

'Semantic Forms' is somewhat vague, so let me clarify.

When I say 'semantic form', I'm talking about a form that would make it easy for people to use semantic identifiers as values in form fields.

Ideally I would like to make it possible for normal people to select terms from a list of human-readable labels, and then save the machine-readable identifiers which correspond to those labels.

URIs for Drupal content?

Are there any guidelines/best practices for assigning URIs for Drupal Linked Data?

I've got the various modules publishing RDF just fine, and can get RDF from URIs like http://hostname/node/xyz/rdf, but this sort of URI is really an implementation detail, and therefore not in the spirit of linked data URIs. It would seem to be much more appropriate to have URIs that might read something like http://hostname/content-type/title.

I've tried using Pathauto, which rewrites the URLs well-enough, but doesn't provide the RDF as expected.

Big News - Google officially announces support for Good Relations RDFa markup

This news came a few days ago... Google is officially supporting the Good Relations (e-commerce) ontology as a source for Rich Snippets.

This means that once we have a good mapping for it in Drupal Commerce, sites that use Drupal for commerce will be at a distinct advantage. Yahoo research showed that click through rates for rich snippety search results were 15% higher, and other research has shown up to 30% higher.

Is D7's default use of the Semantic Web ethical?

Obviously, the title was created was designed to elicit discussion ... but I am seriously interested in the prospects for unintended consequences of D7's default use of RDF. D7 will be a great leap forward, and I'm genuinely excited about the prospects of D7's adoption of RDFa. Upon further reflection, I'm wondering if D7's embrace might actually make it easier for users to be tracked by organizations like Recorded Future. I understand, that today's default settings can be "undone" ... but it is the default that has me most concerned ... precisely because it is the novice end user who isn't particularly savvy that will be put at most risk ... and is unlikely to even know what is going on "under the hood" ... I know, I know ... probably an exaggerated concern, but I thought I'd throw it out there and see if anyone might want to comment.

VIVO WEB - Enabling National Networking of Scientists

Hi everyone,

I was wondering if anyone had any comments on the http://www.vivoweb.org project and it's relationship ship to Drupal. VIVO in a nutshell, is a web application provides a semantic database that can be searched that contains information about scientists, their research interests, affiliations, publications, grants, etc. VIVO is in deployment at several universities and is being expanded through a $12.2m stimulus grant from the National Center for Research Resources (NCRR) of the National Institutes of Health (NIH). see more at http://www.vivoweb.org/about/faq/about-project

Importing and round-tripping RDF in Drupal

Importing catalogues

We need to import arbritary catalogues (spreadsheets) into RDFable Drupal nodes.

We suggest the following as a way forward: before implementing this, we want to see if this would be useful to the broader Drupal RDF community, and whether it is compatible with other existing proposals:

Option 1: Dynamically create content types

For each import format dynamically create a node type that matches the field structure. Provide an RDF mapping for the created node type to enable the imported items to be tagged up with RDF.

Option 2: Define a generic content type for imports

Spreadsheets are imported into two node types. The 'header' includes the spreadsheet file and information about it's structure. A second content type is used to import each row. A row is a list of attributes taken from the column data for that row.

We also need to consider round-tripping issues, as follows:

Implementing Kendra Signpost using Drupal and RDF?

We (the Kendra team) are in a bit of a quandary. We need to implement our EU funded project (Kendra Signpost) using Drupal but we are unsure, given recent D7/RDF announcements, as to which direction to take, namely D6 or D7 and using which modules.

Here is a brief description of what we want to achieve with questions as how to proceed - given that we have developers that can contribute to collaborative efforts so long as there is mutual benefit and we get to build Kendra Signpost.

Overview

  • Kendra is being paid by the EU to build Kendra Signpost which needs to launch middle of 2010. Let's put this EU money to good use.
  • Initially we wanted to build this system using only Drupal 7 but there are a number of modules that are just not ready for us yet. But as soon as Drupal 7 is ready we want to move all projects to it. So, we need to have clear upgrade paths when we choose Drupal modules. And perhaps only work on and contribute to efforts that are both Drupal 6 and 7 simultaneously.
