  1. How to Create EML Packages Using Morpho and Store them in an ILTER Metacat Kristin Vanderbilt Based on material developed by Samantha Romanello and Will Tyburczy

  2. What is EML? • It’s a metadata standard developed by ecologists • EML is a structured format for metadata written in XML

  3. EML (Ecological Metadata Language) looks like this:

  4. EML: • Is not meant for humans to read! • Captures metadata in a structurerd XML format that computers can easily read. • EML from many sites can be put into a single database (a Metacat) so that cross-site searches for data can be done

  5. EML EML Israel LTER Metacat SAEON Metacat JaLTER Metacat EML All ILTER Metacats will be linked, so all metadata can be accessed from a single web page Brazil Metacat TERN Metacat EML US LTER Metacat EML

  6. Search Page for US LTER Metacat A Similar Web Page will be built to search all ILTER metadata This Web Page searches the US LTER Metacat

  7. ILTER Metadata Recommendations • At the 2008 ILTER meeting in Slovakia, the ILTER voted to adopt EML as the ILTER Metadata Standard • It was agreed that ILTER members would create ‘Discovery Level EML’ and submit the EML to network metadata caches (known as Metacats)

  8. ILTER Metadata • ILTER EML packages must have the following elements (in English): • Title • Owner • Abstract • Keywords • Package-ID (A unique identifier for the EML package) • There are many other elements, but only these five are required by the ILTER

  9. These Slides Show: • How to create an EML data package using the Morpho Metadata Editor • How to insert that EML data package into an ILTER Metacat NOTE: A “data package” is a file that contains metadata as EML and may also contain data

  10. What is Morpho? • It provides a way for ecologists to share data by defining a common structure to document their data • It uses an XML format to create the common structure. • So, basically, Morpho is an XML editor

  11. What can Morpho do? • Create EML data packages • Import data in to a data package • Save data packages – both locally and over the network • Search for data packages – both locally and over the network • Open and edit data packages • Export data packages

  12. Let’s get started making a Discovery Level EML Document

  13. First, Register with KNB (Knowledge Network for Biocomplexity) • KNB developed Morpho • By registering with KNB, you can search data in the KNB Metacat and also save your metadata to a Metacat • Registration is necessary in order to use Morpho

  14. Register with KNB • To begin, register as a user at the KNB site http://knb.ecoinformatics.org/index.jsp • Scroll down the page until you find the login & registration box in lower left of the page • Click on the link ‘create a new account’ • Write down your username, organization and password as you will use this in Morpho. Use ‘LTER’ as your organization.

  15. Downloading & Installing Morpho • Next go to http://knb.ecoinformatics.org/morphoportal.jsp to download the most recent version of Morpho (1.8.0). • There is an installer that will walk you through the installation.

  16. Opening Morpho • Once you have installed Morpho. Locate Morpho in your program file and start the application.

  17. Opening Morpho • When you open Morpho for the first time, you will see a New Profile window.

  18. Creating a profile • Enter a name for the profile • Suggested: first initial and last name (kvanderbilt) • Enter your name • Hit “Next”

  19. Creating a profile • Enter the username and affiliation of your KNB account • This is the same username and organization you created on the KNB site • Hit “Next”

  20. Creating a profile • Select an identifier prefix • Usually the same as your account username • Used as the first part of the name of your data packages • Hit “Finished”

  21. Network Login • A screen will open asking you for your password. • This is the same password that you created on the KNB site • By logging in, you can search for data in a Metacat through Morpho and you can contribute your metadata to a Metacat • If you don’t login (Skip Login), your metadata is stored locally

  22. The main window • All controls are accessible via the menu bar • Butterfly icon indicates that program is processing

  23. The main window • All controls accessible via the menu bar • Butterfly icon indicates that program is processing

  24. Logging in • You can see your network status in two places • The main window • The login status icon on the lower right

  25. Logging in • You can see your network status in two places • The main window • The login status icon on the lower right

  26. Try a search for data packages:

  27. Searching for data packages • You can search on your local computer or on the network (which defaults to the KNB Metacat) • You can search multiple terms using “More” • You can combine subject search with taxonomic and spatial constraints

  28. Searching for data packages • You can search on local computer or network (which defaults to the KNB Metacat) • You can search multiple terms using “More” • You can combine subject search with taxonomic and spatial constraints

  29. Searching for data packages • Search on local disks or network • Search multiple terms using “More” • You can combine a subject search with taxonomic and spatial constraints

  30. Searching for data packages • Select taxonomic rank and enter name • Can search multiple taxa using “More”

  31. Searching for data packages • Select taxonomic rank and enter name • You can search multiple taxa using “More”

  32. Searching for data packages: by location • Select area of interest by moving box or enter coordinates by hand • Zoom in to allow greater precision using the graphical box

  33. Searching for data packages • Select area of interest by moving box or enter coordinates by hand • Zoom in to allow greater precision using the graphical box

  34. Searching for data packages • Data packages matching criteria are listed by last modification date • Red icon indicates the package includes data table level EML • Double click a package to open it

  35. Searching for data packages • Data packages matching criteria are listed by last modification date • Red icon indicates the package includes data table level EML • Double click a package to open it

  36. Searching for data packages • Data packages matching criteria are listed by last modification date • Red icon indicates the package includes data table level EML • Double click a package to open it

  37. Start the Wizard to Create EML

  38. Creating a data package:The Data Package Wizard • Step-by-step interface for creating valid EML documents • Required elements are listed in RED • After creating documents, the interface for the various sections is reachable via the “Documentation” menu

  39. Creating a data package:The Data Package Wizard • Step-by-step interface for creating valid EML documents • Required elements are listed in RED • After creating documents, the interface for the various sections is reachable via the “Documentation” menu

  40. Editing Data Packages:Title and Abstract • Enter a descriptive title • Briefly describe the content and purpose of the data in the abstract

  41. Editing Data Packages:Title and Abstract • Enter a descriptive title • Briefly describe the content and purpose of the data in the abstract (note: abstract is not required)

  42. Editing Data Packages:Keywords • Hit “Add” to enter keywords (required)

  43. Use the first radio button when adding keywords • Hit ‘Add’ and enter a keyword in the space provided. • To edit or delete existing keywords, select them and hit the ‘Delete’ button

  44. Editing Data Packages:Data Set Owner • To add an owner, hit “Add” (required) • To edit or delete an owner, select the listing, then hit the appropriate button

  45. Editing Data Packages:Data Set Owner • To add an owner, hit “Add” (required) • To edit or delete an owner, select the listing, then hit the appropriate button

  46. Editing Data Packages:Data Set Owner • Enter in the information for the owner, then hit “OK” • You have to enter one of the red-labeled entities: either enter Last Name, Organization (e.g., Sevilleta LTER) or Position Name (e.g., Sevilleta IM)

  47. Editing Data Packages:Contact Person • Works similarly to data set owners • To add a contact, hit “Add”

  48. Editing Data Packages:Contact Person • You can select a previous entry in the data package to specify the same person • You can also specify a person from another data package

  49. Editing Data Packages:Contact Person • You can select a previous entry in the data package to specify the same person • You can also specify a person from another data package

  50. Editing Data Packages:Contact Person • To select an entry from another data package: • select the package on the left • then the contact on the right
