Create a Schema using TOM.Net API

I was a little frustrated today for not finding out soon enough about the SchemaFields class. Basically that's the class you need when creating a Schema programmatically using TOM.Net API in SDL Tridion 2011.

Creating the Schema is easy -- just use the new Schema(session, parentTcmUri) constructor, but creating the fields themselves is a bit tricky. You have to use the SchemaFields class, just like you would use ItemFields on a normal Component fields or on any Metadata fields collections.

The code below creates a Schema and adds one RTF field to it and one Keyword based field to its metadata fields:

Session session = new Session();

Schema schema = new Schema(session, new TcmUri("tcm:20-1-2")) {
    Title = "New Schema",
    Description = "Schema Description"

SchemaFields fields = new SchemaFields(schema);
fields.Fields.Add(new XhtmlFieldDefinition("NewField") {
    Description = "New Field Description",
    MinOccurs = 1, // mandatory
    Height = 5

KeywordFieldDefinition metaField = new KeywordFieldDefinition("MetaField") {
    Description = "New Meta Field Description",
    Category = new Category(new TcmUri("tcm:20-859-512"), session)
metaField.List.Type = ListType.Tree;

schema.Xsd = fields.ToXsd();

Toolkit - Dynamic Content Queries

This post if part of a series about the  File System Toolkit  - a custom content delivery API for SDL Tridion. This post presents the Dynamic Content Query capability. The requirements for the Toolkit API are that it should be able to provide CustomMeta queries, pagination, and sorting -- all on the file system, without the use third party tools (database, search engines, indexers, etc). Therefore I had to implement a simple database engine and indexer -- which is described in more detail in post Writing My Own Database Engine . The querying logic does not make use of cache. This means the query logic is executed every time. When models are requested, the models are however retrieved using the ModelFactory and those are cached. Query Class This is the main class for dynamic content queries. It is the entry point into the execution logic of a query. The class takes as parameter a Criterion (presented below) which triggers the execution of query in all sub-criteria of a Criterio

A Implementation - Custom Binary Publisher

The default way to publish binaries in DD4T is implemented in class DD4T.Templates.Base.Utils.BinaryPublisher and uses method RenderedItem.AddBinary(Component) . This produces binaries that have their TCM URI as suffix in their filename. In my recent project, we had a requirement that binary file names should be clean (without the TCM URI suffix). Therefore, it was time to modify the way DD4T was publishing binaries. The method in charge with publishing binaries is called PublishItem and is defined in class BinaryPublisher . I therefore extended the BinaryPublisher and overrode method PublishItem. public class CustomBinaryPublisher : BinaryPublisher { private Template currentTemplate; private TcmUri structureGroupUri; In its simplest form, method PublishItem just takes the item and passes it to the AddBinary. In order to accomplish the requirement, we must specify a filename while publishing. This is the file name part of the binary path of Component.BinaryConten

Scaling Policies

This post is part of a bigger topic Autoscaling Publishers in AWS . In a previous post we talked about the Auto Scaling Groups , but we didn't go into details on the Scaling Policies. This is the purpose of this blog post. As defined earlier, the Scaling Policies define the rules according to which the group size is increased or decreased. These rules are based on instance metrics (e.g. CPU), CloudWatch custom metrics, or even CloudWatch alarms and their states and values. We defined a Scaling Policy with Steps, called 'increase_group_size', which is triggered first by the CloudWatch Alarm 'Publish_Alarm' defined earlier. Also depending on the size of the monitored CloudWatch custom metric 'Waiting for Publish', the Scaling Policy with Steps can add a difference number of instances to the group. The scaling policy sets the number of instances in group to 1 if there are between 1000 and 2000 items Waiting for Publish in the queue. It also sets the
