BuRST format adaption discussion

From Stellar Deliverable 6.3

1 General proposals for the format

This document is intended for discussion of a second version of the publication feed format. Mandatory pieces are referred to with 'MUST', optional stuff is labeled with 'CAN'.

1.1 Entity representations

Represent entities in vCard to include location data (proposal by Till Nagel). Example:

<v:VCard rdf:about="http://www.cs.kuleuven.be" >
	<v:fn>K.U. Leuven</v:fn>
	<v:org>
		<rdf:Description>  
			<v:organisation-name>K.U. Leuven</v:organisation-name>
			<v:organisation-unit>Dept. Computer Science</v:organisation-unit>
		</rdf:Description>  
	</v:org>
	<v:adr>
		<rdf:Description>  
			<v:street-address>Celestijnenlaan 200A</v:street-address>
			<v:locality>Heverlee</v:locality>
			<v:postal-code>3001</v:postal-code>
			<v:country-name>Belgium</v:country-name>
			<rdf:type rdf:resource="http://www.w3.org/2006/vcard/ns#Work"/>

	<v:logo rdf:resource="http://www.cs.kuleuven.be/cs/includes/common/_i/logo-kuleuven.gif"/>   
</v:VCard>

2 Proposals for additional metadata needed in the feeds

Include swrc:cite and swrc:citedBy in the standard

Include swrc:doi in the standard - I don't think its safe or sensible to use swrc:isbn to represent this, but I do think doi is vital to help with disambiguation. I also note that including swrc:isbn in <swrc:Article> or <swrc:Book> renders the feed invalid - if correct, the documentation needs to reflect this.

3 Proposals for the existing metadata

3.1 CHANNEL

Describes the elements which MUST be present in the channel (describing properties of the collection of publications in the feed).

3.1.1 Root element

	Class	Subclasses/Format of literal	Properties (description)	optional	Comments	Proposals
Channel	channel	see table below	rdf:about (uri of the channel)

3.1.2 Subclasses of channel

Elements describing the properties of the collection.

	Property	Subclasses/Format of literal	optional	Comments	Proposals
Title of the collection	title	free text
Description of the collection	description	free text
Link to collection/publisher	link	url		e.g. a link to the collection or to the homepage of the publisher	Use RFC 1738 http://www.faqs.org/rfcs/rfc1738.html
Last update	dc:date	date in the format: YYYY-MM-DDThh:mm:ssTZD (eg 1997-07-16T19:20:30+01:00), whereby TZD is the time zone designator and describes the offset from the UTC		http://www.w3.org/TR/NOTE-datetime. We need this to ensure proper updating.
Publisher of feed	dc:publisher	free text	yes		Define a format for institutions
Items	items	rdf:Seq		Items in the sequence as they appear in the feed

3.1.3 Sublasses of rdf:Seq

URIs of all publications must be listed here.

	Property	Subclasses/Format of literal	Properties (description)	optional	Comments	Proposals
Item	rdf:li		rdf:resource (uri of the publication)

3.2 ITEMS

3.2.1 Root element

	Property	Subclasses/Format of literal	Properties (description)	optional	Comments	Proposals
Item	item	see table below	rdf:about (uri of the item) xml:lang (language of the item - optional)		The URI must be the same as in the items list in the channel. Items must be also be in the same sequence	Specify a list of languages that are available; we could use 639.1 http://www.loc.gov/standards/iso639-2/php/code_list.php

3.2.2 Sublasses of item

Put here all the information that you would like to have displayed in feed readers/applications capable of displaying RSS feeds. This is not the metadata commonly perused by the Open Archive. This information should be ennclosed in burst:publication (see below)

	Property	Subclasses/Format of literal	optional	Comments	Proposals
Title of publication	title	free text
Description of publication	description	free text
Link to the publication	link	url		If available, put here the link to the fulltext. Otherwise a link to page where the publication can be obtained.	Use RFC 1738 http://www.faqs.org/rfcs/rfc1738.html
Last update	dc:date	date in the format: YYYY-MM-DDThh:mm:ssTZD (eg 1997-07-16T19:20:30+01:00), whereby TZD is the time zone designator and describes the offset from the UTC		http://www.w3.org/TR/NOTE-datetime We need this to ensure proper updating.
Authors	dc:creator	LASTNAME, FIRSTNAME; LASTNAME, FIRSTNAME,...	yes
Keywords	dc:subject	free text	yes	Use a tag per keyword	Define characters that are not allowed, e.g. comma, semicolon
Connection to publication metadata	burst:publication	see table below

3.2.3 Subclasses of burst:publication

The link between the RSS item and the RDF metadata part is done by burst:publication. First, specify the document type (take one ot the classes below):

Document type	Class	Subclasses/Format of literal	Comments
Unspecified publication	swrc:Publication	see table below
Publication in journal	swrc:Article	see table below	There seems to be no way to express the quality (peer-reviewed or not) in SWRC
Publication in conference proceedings	swrc:InProceedings	see table below	There seems to be no way to express the quality (peer-reviewed or not) in SWRC
Book chapter	swrc:InBook	see table below
Book	swrc:Book	see table below
Research report	swrc:ProjectReport	see table below
Proceedings	swrc:Proceedings	see table below
Thesis	swrc:Thesis	see table below	We could be even more specific here; swrc offers MasterThesis and PhDThesis as subclasses
Other	swrc:Misc	see table below
Document type: Workshop	swrc: Workshop	see table below	swrc:Workshop is actually a subclass of swrc:Event

3.2.4 Subclasses of document type

Put here all the metadata you have about the publication:

Root element	Class/Property	Subclasses/Format of literal	Properties (description)	optional	Comments	Proposals
Author	swrc:author	swrc:Person			Fallback: dc:creator.
Title	swrc:title	free text	xml:lang (language of the title - optional)		Fallback: title	Specify a list of languages that are available; we could use 639.1 http://www.loc.gov/standards/iso639-2/php/code_list.php
Writing year	swrc:year	YYYY			e.g. 2009
Writing month	swrc:month	MM		yes	e.g. 06
Publication date	swrc:date	YYYY-MM-DD		yes	In case you want to be more specific, you can use this instead of swrc:year and swrc:month. e.g. 2009-06-17
Abstract	swrc:abstract	free text		yes	Fallback: description. I'm not to sure about this fallback though - The item description may contain more/different content than the original abstract.
Book title	swrc:booktitle	free text			The title of the containing publication. Could also be the title of the proceedings, or a journal title
Commercial Editor (publisher)	swrc:publisher	free text		yes
Conference title	swrc:atEvent	free text		yes	Specify conference, e.g. ECTEL 2009
ISBN	swrc:isbn	isbn		yes	e.g. 978-3-642-04635-3
Keywords	swrc:keywords	keywords separated by comma		yes	Fallback: dc:subject
Pages	swrc:pages	FROM_PAGE-TO_PAGE		yes	e.g. 99-110	Allow one number as well for one-pagers
Place	dc:spatial	CITY, COUNTRY		yes	Unfortunately, there is no geographical information in swrc. e.g. Graz, Austria	Use genoames here .. We need better location data than just city and country
Project	swrc:describesProject	free text		yes	Specify name of the project here
Research team	swrc:projectInfo	free text		yes	Specify research group here
Scientific Editor	swrc:editor	swrc:Person		yes
Series	swrc:series	text (series)		yes
Volume	swrc:volume	text (volume)		yes

3.2.5 Subclasses of swrc:Person

Put here all the metadata you have about the authors/editors:

Root element	Class/Property	Subclasses/Format of literal	Properties (description)	optional	Comments	Proposals
Name	swrc:name	LAST NAME, FIRST NAME
Affiliation	swrc:affiliation	free text		yes	Specify organization here

        <swrc:abstract>Work-integrated learning (WIL) poses unique challenges for user model design: on the one hand
        users’ knowledge levels need to be determined based on their work activities – testing is not a
        viable option; on the other hand users do interact with a multitude of different work applications –
        there is no central learning system. This contribution introduces a user model and corres-ponding services
        (based on SOA) geared to enable unobtrusive adaptability within WIL environments. Our hybrid user model
        services interpret usage data in the context of enterprise models (semantic approaches) and utilize heuristics
        (scruffy approaches) in order to determine knowledge levels, identify subject matter experts, etc. We give an
        overview of different types of user model ser-vices (logging, production, inference, control), provide a
        reference implementation within the APOSDLE project, and discuss early evaluation results.</swrc:abstract>
