Information Architecture and Faceted Navigation in SharePoint 2010

SharePoint 2010 has new features included (such as Taxonomy, Document Sets) and search improvements (such as Refiners). This has brought in a whole lot of changes to the thought process related to information architecture.

In MOSS 2007, we dealt with a linear guided navigation. SPS2010 improvements and new features introduced faceted navigation. It is also referred as faceted search or (free form) guided navigation. The faceted search presents users with a list of relevant suggestions for refining the search results by document type, site, author, modified date, tags etc.

Information architecture is the key in designing the content management systems, knowledge management portals, e-Commerce sites and so on. Consider below points while deciding on Information architecture.

• Content Roll up: Using Content Query web part, relevant and related content can be made available on content pages, document set welcome pages etc. Content Query web part has few improvements related to managed metadata (taxonomy) columns. Read here what’s new in content query web part.
• Refiners: This is a key to faceted search. The refinement web part can be used to narrow the search results.
• Extensibility of Search Web part: SPS 2010 has search web parts which can be extended. In MOSS 2007, these web parts are sealed. Scenario based search functionality can be extended and used on various pages, document set pages.

I have listed here few of the points. There are many features in SPS 2010 which we can exploit for the better information architecture and good navigation providing better user experience.
Few links about faceted search and information architecture.

SharePoint: Site Columns and Content Types

There are various posts on the internet describing the site columns and content types. In this post I am co-relating these with concepts of objects and classes. This will help the developer visualize these concepts differently.

Content and Object

Object has data. Class provides the set of attributes to detail the object instances.

Content is data. Content has two categories: Structured and Unstructured.

Content comprises of documents and list items. Content does not include list or library itself. List or library helps user to organize the content.

Structured content is the one which separates its storage from its display. e.g. List Items can be sorted/filtered and viewed in List web part or data row in a SQL data table.

Unstructured content is the one which cannot be viewed separately the format in which they are stored. e.g. Word document cannot be viewed without the MS Office Word.

Content type provides the set of attributes to define the metadata about content. The attributes are provided in the form of columns/fields in the list or at the site level.

Site Column

When the column is defined at site level, it is a site column. The site column is reusable across all lists and libraries in the site.

This is very similar to have property declared in an interface and will be available across all objects implementing the interface.

Content Type

Content type is a set of site columns. The site column helps in describing the content. The content type can be used across the lists and libraries in the site.

This is just like a complex data type. The data types/ classes has properties to describe the object.

Document Library Creation with Specific Document Template Using Server Object Model

Introduction: There is no way in SharePoint UI to create a document library with blank Excel/PowerPoint document template. But it is possible to create a document library with such document templates programmatically.

Technicalities:
I will first take you through the classes involved in development.


  • SPListCollection

  • SPListTemplateType

  • SPListTemplate

  • SPDocTemplate


SPListCollection has Add method with 7 overloads. Look for the method signatures here.



We will concentrate on the following signature:



public virtual Guid Add(
string title, //Title for the library
string description,//Description about the library
SPListTemplate template,//The list template. We are interested in Document Library.
SPDocTemplate documentTemplate //The document template for library.e.g. Excel, Word or Powerpoint etc.
)

SPListTemplateType is a enumeration. The enumeration has underlying integer values which match the Type attribute of ListTemplate element. Please visit here for details.


SPListTemplate represents the list definition or list template for the list. The list definition/template has the views and fields defined. SPWeb.ListTemplates returns the list definitions for the web site. SPSite.GetCustomListTemplates method returns the list template collection for the site collection. More details.



SPDocTemplate represents the document template. Whenever we create a document library, it is created by using blank Word Document template. There are many document templates available in SharePoint 2010 OOB. The document templates have IDs. The ID is used to filter the document template collection presented by SPWeb.DocTemplates property. Document Template IDs list follows:












Document Template IDDescription
101A blank Microsoft Word 97-2003 document.
103A blank Microsoft Excel 97-2003 document.
104A blank Microsoft PowerPoint 97-2003 document.
105A blank Microsoft basic page ASPX document.
106A blank Microsoft Web Part Page ASPX document.
111A basic Microsoft OneNote 2010 Notebook.
121A blank Microsoft Word document.
122A blank Microsoft Excel document.
123A blank Microsoft PowerPoint document.


Code:

using (SPSite site = new SPSite(serverUrl)) {
using (SPWeb web = site.OpenWeb()) {
SPListTemplate lstTemplate = web.ListTemplates["Document Library"];
SPDocTemplate docTemplate =(from SPDocTemplate dt in web.DocTemplates
where dt.Type == 122
select dt).FirstOrDefault();
Guid newLibID =
web.Lists.Add("Expense Claims", "Excel Expenses", lstTemplate, docTemplate);
SPDocumentLibrary newLib = web.Lists[newLibID] as SPDocumentLibrary;
newLib.OnQuickLaunch = true;
newLib.Update();
}
}



The code is for console application.(I know you are aware, just for clarity).
