Poll Question #1: FME
How long have you been using FME?
?
Metadata – What is it?
Metadata – What it is
Metadata provides information about whatever types of data you have:
12
Metadata – Data about data
Describes data structures• tables• geometry types• data types• fields
Describes data content• coordinate system• extent• modification date• quality, ownership, etc.
Metadata - Purpose
Common Metadata Questions
What does the data set describe?Who produced the data set?Why was the data set created?How was the data set created?How reliable are the data; what problems remain
in the data set?How can someone get a copy of the data set?Who wrote the metadata?

Poll Question 2: Metadata
How often do you work with metadata?
?
Metadata Standards
FGDC & ISO 19115 • describes geographical
information and services
• contents, spatial-temporal, data quality, access and rights to use
• 400 metadata elements, 20 core
ISO / OGC Standards
ISO/TS 19139• defines Geographic Meta Data XML (gmd) • XML Schema implementation derived from ISO
19115• Version "2007-04-17" uses GML 3.2.1
(http://www.opengis.net/gml/3.2)• Version "2006-06-04" use GML 3.2.0 (http://
www.opengis.net/gml)• ISO 19119 – web services
Bottom line: need to know what GML version and what ISO standard you need to comply with
Poll Question #3: Standards
Which metadata standards/types are interested in?
?

Poll Question 4: XML
What XML tools do you use?
?
Validation – What to validate against?
ISO 19139 with GML 3.2.0:http://schemas.opengis.net/iso/19139/20060504/gmd/gmd.xsd
To Validate XML against ISO 19139 with GML 3.2.1:http://standards.iso.org/ittf/PubliclyAvailableStandards/ISO_19139_Schemas/
See page 13 of:http://
inspire.jrc.ec.europa.eu/reports/ImplementingRules/metadata/MD_IR_and_ISO_20090218.pdf
Or Google and click top link: “inspire metadata implementing rules technical guidelines”
Key takeaway: to validate gmd:MD_Metadata you need to validate against gmd.xsd
Demo: Validation
XMLValidator• Syntax• Schema
Validation Report – Bad Syntax
Validation Report – Bad Schema
Validation Report – Good Metadata
Validation Workspace
Other Validation Options
• Tester• Field names• Data types (numeric, date etc)• IDs
• CoordinateSystemExtractor• GeometryFilter• GeometryOGCvalidator• SpatialFilter (check extents)
CSW: Catalog Service for the Web
• Deegree
• GeoNetwork
• OpenGIS
• TerraCatalog
Metadata Services: CSW
• Reading• Writing / Publishing• Updating
Poll Question #5: CSW
What CSW tools do you use?
?
Arkansas Geostor: Download
Customer Implementations: LGII – Lithuania Geospatial Portal
File Formats: AutoCAD DXF / DWG ESRI Personal Geodatabase Shape MapInfo TAB Microstation Design V8 GML GIF / PNG JPEG TIFF ERDAS IMG ECW
Coordinate systems: LKS94 WGS84 ETRS89 1963 Pulkovo 1942 UTM (34, 35 zones)

Summary
Metadata describes your dataHelps with searches and
managementFME can help drive your metadata: • Read / write and update• Harvest• Validate• Automate maintenance tasks• Integrate with CSWSwitch from manual to automatic by
using FME to power your metadata
