XML, Metadata and More!

Transcription

1 XML, Metadata and More! What is XML? A robust and useful mark-up language Meta-language Allows for reformatting of data through style sheets XML defines the structure of a document DTD - Document Type Definition Used to create a set tags to define a schema Different industries/companies would have different schemas 1

2 To design for XML conversion - you need to know the schema What are the tags? Your content needs to correspond to the right tags A Structured Language XML is well defined and predictable Has a specific vocabulary and method for defining structure <headline>this is about XML <headline> The headline itself is the element Attributes can be applied to the data Attributes are considered modifiers of the element and can contain metadata XML Driving HTML XML needs to be interpreted into something the browser can use Cascading Style Sheets The style sheet contains the presentation specifics of the document 2

3 Best Uses for XML Repetitive data Data that needs to be repurposed Database driven data Needs to publish to a site that has the correct server technologies to support dynamic web page creation ASP, JSP,PHP XML Conversion So the thought of coding makes you glaze over. Vendor solutions Quark lang=1&page=quarkxpressconverter InDesign Conversion tools can be expensive InDesign lets you write tags for XML Someone must designate the tags (set up the schema) You then create the corresponding tags in InDesign through the Tags Panel 3

4 Correct syntax is required The tags are then linked to the corresponding data in your document You view your structure through the Structure Pane InDesign exports the file to XML Code in Netscape - no style sheets applied 4

5 Off The Shelf Exporters atomik/overview.epml The benefits of XML in a Cross-Media world is that it allows for repurposing of original content to a variety of destinations through a structured coding scheme Metadata Data about data Structured Is attached to a file, but not viewed unless accessed A powerful tool for organizing information Useful for databases 5

6 The Web According to W3C, it is machine understandable information for the web Valuable for search engines The Importance of Metadata Beyond search engines- Will allow true automation in the graphics industry Provides contextual information that travels with a file Searchable, editable and indexable Software apps can be designed to read, edit and take action on a files metadata PRISM Metadata and Photography Becoming a critical file component EXIF data - recorded at the time of the shot 6

7 Entered Metadata on Individual File Through Photoshop File Browser, file info Through File Info Bridge Adobe Bridge is a powerful, easy-touse media manager that lets you easily organize, browse, locate, and view creative assets (Adobe) It is your Starship Command for the CS Suite (Dolin) 7

8 Automate Metadata Through Bridge Bridge provides centralized access to project files and global settings, as well as to XMP metadata tagging and searching capabilities. Video demonstrating Bridge and Metadata (Keywords) DISC Digital Image Submission Criteria A national working group formed to develop a set of specifications for image submission Instead of stamping a slidemount Fill in the correct data fields The DISC panel can be added to Photoshop 8

9 Metadata in Databases Extensis Portfolio XMP extensible Metadata Platform Developed by Adobe An open framework - goal is to develop a defacto standard for a metadata labeling system Built on two basic standards ; RDF and XML RDF Resource Description Framework Specific syntax and schema that provided a formal specification of how to structure a given set of metadata Takes the way something is described and translates it into a label 9

10 XMP provides a framework This framework consists of 3 major parts 1) The syntax 2) The packet technology which describes the info in the file 3) The specifications which describes how the standards are supported Metadata allows your files to indicate where they've been, where they are going, where they came from, and what they are about Gunar Penakis, Adobe 10

11 XML, Metadata and XMP help manage and sort all the file data used in a cross-media workflow Content needs to be created once, repurposed many times! 11
