This document provides an overview of AtomPub servers and how to implement them using the Catalyst::Controller::Atompub module in Perl. It defines what AtomPub is, its data model and five basic operations. It compares AtomPub to other RESTful APIs like Amazon S3, discussing how AtomPub uses richer metadata separated from data with URIs determined by servers. The document recommends Catalyst::Controller::Atompub for building an AtomPub server as it handles the core AtomPub logic, allowing developers to focus on their application logic and customizing aspects like URIs. Sample code is provided for basic CRUD operations and customizing URI generation.

RESTful Data Services with the ADO.NET Data Services Frameworkgoodfriday
Learn how to use ADO.NET Data Services Framework to easily create and consume REST data services on the web. This session will cover the main concepts of the ADO.NET Data Services Framework (aka Project "Astoria"), show how to use it, and discuss how to use it with Microsoft's broader vision of a common interface for Windows Live and 3rd party services.
This session describes the architecture and implementation of an embeddable, extensible enterprise content management core for Java EE and simpler platforms. The presentation starts by describing the general architectural concepts used as building blocks:
• A schema and document model, reusing XML schemas and making good use of XML namespaces, where document types are built with several facets
• A repository model, using hierarchy and versioning, with the Content Repository API for Java (JSR 170) being one of the possible back ends
• A query model, based on the Java Persistence query language (JSR 220) and reusing the path-based concepts from Java Content Repositories (JCR)
• A fine-grained security model, compatible with WebDAV concepts and designed to provide flexible security policies
• An event model using synchronous and asynchronous events, allowing bridging through Java Message Service (JMS) or other systems to other event-enabled frameworks
• A directory model, representing access to external data sources using the same concepts as for documents but taking advantage of the specificities of the data back ends
Suitable abstraction layers are put in place to provide the required level of flexibility. One of the main architectural tasks is to find commonalities in all the systems used (or whose use is planned in the future) so framework users need to learn and use a minimal number of concepts. The result is a set of concepts that are fundamental to enterprise document management and are usable through direct Java technology-based APIs, Java EE APIs, or SOA. The presentation shows, for each of the main components, which challenges have been met and overcome when building a framework in which all components are designed to be improved and replaced by different implementations without sacrificing backward compatibility with existing ones.
The described implementation, Nuxeo Core, can be embedded in a basic Java technology-based framework based on OSGi (such as Eclipse) or in one based on Java EE, according to the needs of the application using it. This means that the core has to function without relying on Java EE services but also has to take advantage of them when they are available (providing clustering, messaging, caching, remoting, and advanced deployment).

RMD24 | Debunking the non-endemic revenue myth Marvin Vacquier Droop | First ...BBPMedia1
Marvin neemt je in deze presentatie mee in de voordelen van non-endemic advertising op retail media netwerken. Hij brengt ook de uitdagingen in beeld die de markt op dit moment heeft op het gebied van retail media voor niet-leveranciers.
Retail media wordt gezien als het nieuwe advertising-medium en ook mediabureaus richten massaal retail media-afdelingen op. Merken die niet in de betreffende winkel liggen staan ook nog niet in de rij om op de retail media netwerken te adverteren. Marvin belicht de uitdagingen die er zijn om echt aansluiting te vinden op die markt van non-endemic advertising.
RMD24 | Retail media: hoe zet je dit in als je geen AH of Unilever bent? Heid...BBPMedia1
Grote partijen zijn al een tijdje onderweg met retail media. Ondertussen worden in dit domein ook de kansen zichtbaar voor andere spelers in de markt. Maar met die kansen ontstaan ook vragen: Zelf retail media worden of erop adverteren? In welke fase van de funnel past het en hoe integreer je het in een mediaplan? Wat is nu precies het verschil met marketplaces en Programmatic ads? In dit half uur beslechten we de dilemma's en krijg je antwoorden op wanneer het voor jou tijd is om de volgende stap te zetten.

Implicitly or explicitly all competing businesses employ a strategy to select a mix
of marketing resources. Formulating such competitive strategies fundamentally
involves recognizing relationships between elements of the marketing mix (e.g.,
price and product quality), as well as assessing competitive and market conditions
(i.e., industry structure in the language of economics).
The world of search engine optimization (SEO) is buzzing with discussions after Google confirmed that around 2,500 leaked internal documents related to its Search feature are indeed authentic. The revelation has sparked significant concerns within the SEO community. The leaked documents were initially reported by SEO experts Rand Fishkin and Mike King, igniting widespread analysis and discourse.

Putting the SPARK into Virtual Training.pptxCynthia Clay
This 60-minute webinar, sponsored by Adobe, was delivered for the Training Mag Network. It explored the five elements of SPARK: Storytelling, Purpose, Action, Relationships, and Kudos. Knowing how to tell a well-structured story is key to building long-term memory. Stating a clear purpose that doesn't take away from the discovery learning process is critical. Ensuring that people move from theory to practical application is imperative. Creating strong social learning is the key to commitment and engagement. Validating and affirming participants' comments is the way to create a positive learning environment.

POST: Creates a new member
(Member URI is assigned by the server)
PUT:
DELETE:
Updates a member
Deletes a member
GET: Retrieves a member
GET: Lists members in the collection
Operations against Members
Operations against Collections
7. Operations in depth
– Entry and Media Resources
Entry and Media Resources
Two sides of the same coin

PUT: Updates the Member
Entry
link
Metadata MUST be updated
Metadata: at the same time
- escribes attributes of the data: date, author, etc.
D
- as a link to the data
H
- utomatically generated as an Entry by the server
A
8. Role of AtomPub Servers
List + CRUD operations
Supports publishing and editing Web resources
Assigns Member URIs when they are POSTed
Maintenance of metadata
Generates corresponding Entries when POSTed
Updates attributes when the corresponding data is PUTed or DELETEd
Others
Service description in Service Documents (not discussed in my talk)
HTTP processings: Authentication, cache, version control, and error handling
Compared with simple RESTful APIs, AtomPub servers have strong authority
9. Better choose AtomPub for your Web
service?
Myths of AtomPub
AtomPub is a protocol just for blogging
AtomPub is the best one to publish ANY type of Web
resources
Which service is suited for AtomPub?
Text-orientd services, such as blogging and SNS?
File management systems including binary data?
Something else?
10. AtomPub is one of REST instances
AtomPub is one of the REST instances
Don’t choose AtomPub if your service is NOT RESTful
Compare AtomPub with other RESTful APIs if your service is RESTful
Common features of RESTful services (in my talk)
Addresses resources by URIs
CRUD resources by HTTP methods: GET, POST, PUT, and DELETE
Resource type is not an issue: plain-text, XML, images, videos, …
Data model of dataset including several items (see figure)
Set
Item
11. What’s the difference in RESTful APIs?
Metadata
Which kinds of metadata are needed?
Where are metadata placed?
URIs
Who determines resource URIs?
Other options
Search queries, representations, etc.
Comparing AtomPub with a contrasting API, Amazon S3
Matrix of metadata and URIs
URIs Metadata
Simple and with data
Rich and separated from data
By servers
AtomPub
By clients
Amazon S3
12. Amazon S3 (Simple Storage Service)
Metadata
/yapc.asia
Placed in HTTP headers
yapc2008.png
Line-by-line syntax
Always along with data in HTTP body
URIs
Determined by clients
PUT is requested with a URI to create a resource
URI
PUT /yapc.asia/yapc2008.png HTTP/1.1
Content-Type: image/png
Metadata

Example of HTTP request
13. AtomPub
Metadata
Has its own URI and independent from data
12345678.atom
Written in Atom entry
12345678.png
/images
URIs
Entry
Determined by servers
<?xml version=“1.0” encoding=“utf-8”?>
<entry xmlns=“http://www.w3.org/2005/Atom”>
<link rel=“edit”
href=“/images/12345678.atom”/>
<link rel=“edit-media”
href=“/images/12345678.png”/>
<content src=“/images/12345678.png”
type=“image/png”/>
…
</entry>
Metadata: /images/123456578.atom
Data: /images/12345678.png
14. Embedded AtomPub
– Actually, this is AtomPub in usual sense
Metadata
Has it own URI and independent from data
first_entry.atom
Written in Atom entry
Text/XML data can be embedded in metadata
eg. atom:content element
Entry
URIs
/blog
Determined by servers
Suggested by requests with Slug header
POST /blog HTTP/1.1
URI suggestion
Slug: first_entry
<?xml version=“1.0” encoding=“utf-8”?>
<entry xmlns=“http://www.w3.org/2005/Atom”>
<updated>2008-05-15T01:23:45Z</updated>
Metadata
<author><name>yapc</name></author>
…
Data
<content type=“text”>This is my first entry</content>
</entry>
Example of HTTP request
15. Positioning AtomPub in RESTful services
Characteristics of AtomPub
With rich metadata and mainly controlled by servers
Can be changed by embedded content and Slug header options

16. Better choose AtomPub for your Web
service?
Services, which are suited for AtomPub
Metadata is represented in XML, especially in Atom Entries
Atom standard elements are required: author, category, copyright, …
Linked to other resources: eg. a blog entry including pictures
XML vocabularies are used in the metadata: OpenSearch, RDF, …
Complicated data model is acceptable, or don’t use media resources
URIs are determined by servers
Or determined based on clients’ suggestions
I
f you choose AtomPub, go for Catalyst::Controller::Atompub
17. Catalyst::Controller::Atompub
A Catalyst controller class for processing AtomPub
Why controller?
AtomPub defines CONTROL flow for publishing and editing Web resources
Tested in AtomPub Interop
July 2007 at Tokyo
Nov 2007 on the Internet
Feb 2008 at Tokyo
Download from CPAN
18. Catalyst::Controller::Atompub
Makes you focus on your task (eg. Model implementation)
Dispatches requests based on URI and HTTP method
Check cache or version of the requested resources (optional)
Validates requested Entry if exists
Determines a new member URI when POST
by C::C::Atompub
Stores resources to, or retrieves them from databases
Modifies the resources (optional)
Your turn
by C::C::Atompub
Constructs HTTP response and sends it to client
Can overwrite default behavior
19. Sample code – Creating resources
# Attribute :Atompub(create) is required
sub create_entry :Atompub(create) {
my($self, $c) = @_;
# URI of the new Entry, which was determined by C::C::Atompub
my $uri = $self->entry_resource->uri;
# datetime, which was assigned by C::C::Atompub
my $edited = $self->edited;
# POSTed Entry, an XML::Atom::Entry objcet
my $entry = $self->entry_resource->body;
# Creates the new Entry
$c->model('DBIC::Entries')->create({
uri => $uri,
edited => $edited->epoch,
xml => $entry->as_xml,
});
# Returns true on success
return 1;
}
20. Sample code – Listing resources
# Attribute :Atompub(list) is required
sub get_feed :Atompub(list) {
my($self, $c) = @_;
# Skeleton of the Feed, an XML::Atom::Feed objcet,
# was prepared by C::C::Atompub
my $feed = $self->collection_resource->body;
# Retrieve Entries sorted in descending order
my $rs = $c->model('DBIC::Entries')
->search({}, { order_by => 'edited desc' });
# Adds Entries to the Feed
while (my $member = $rs->next) {
my $entry = XML::Atom::Entry->new($member->xml);
$feed->add_entry($entry);
}
# Returns true on success
return 1;
}
21. Sample code – Changing default URIs
eg. /collection/20080515-012345-123456.atom -> /collection/joe/birthday.atom
# Changes Edit URIs, that is URIs for Member resources
sub make_edit_uri {
my($self, $c, @args) = @_;
# Default URIs for Entry (and Media) resources
my($edit_uri, $edit_media_uri) = $self−>NEXT::make_edit_uri($c, @args);
# Modify the URIs as you like...
# Returns modified URIs
return ($edit_uri, $edit_media_uri);
}
# Changes Collection URI
sub make_collection_uri {
my($self, $c) = @_;
# Constructing the new Collection URI as you like...
# Returns the Collection URI
return $new_uri;
}
